Thanks for the continued interest...,

A search of the local public libraries turned up a 1964 MOTOR repair manual with Pontiac Tempest content.  Mated to relevant reference, seen below is the rear axle assembly taking shape combining GMP Trans Am Camaro brake discs/driveshaft and U-joints, a '68 Lane Firebird B.O.P. differential and other scratch built aspects consistent with coming up with something acceptable.  Negative camber is designed into the unit, whereas the missing half of each of the axle tubes has been added here.  A length of brass rod passes through the diff. into each respective axle tube consistent with creating something strong enough to maintain structural integrity for handling.  Thanks...

A replacement floor fabricated for the Gray Ghost led nowhere given the dimensions and shape were wrong.  Too much pondering, too much speculation regarding where to add mass and disguise the underlying mess followed.  A fresh start here then; i.e. a new interior floor with minimal cutting to accommodate the transmission as well as a newly fabricated roll cage to debut here if you will.  The old cage is seen in the first image, evidencing an incorrect and prim main roll hoop profile (note the tightly controlled bends nearest the beltline) whereas the actual article is more 'soft pretzel' in shape if anything at all.  In point of fact the triangulation for siting the 'X' member within the profile of the main hoop is slightly off on the real Gray Ghost cage with the topmost extent of the 'X' not quite meeting up with the furthest extent of the 90 degree bend on each corner.  Further things to notice is that the A-pillar tubes rushed too far forward, extending around the dashboard when they ought to have dove down to terminate atop the floor just forward of the dash stamping.  I've also angled the main roll hoop back slightly top-to-bottom given I missed this detail first go 'round, whereas the dip in the tubes heading back toward the main hoop, faint at best on cage #1, are here more prominent.  Quite a bit better.  Thanks...

Greetings and thanks for the lasting kind notice,

I had failed to note over the course of weeks that interference encountered for fit between the front half of the roll cage was in fact attributable to interference between the transmission and a too-shallow transmission hump as meagerly reproduced on the Sun Star interior floor casting.  A brief attempt to mate a 1:18 ERTL '70 1/2 Camaro transmission and drive shaft tunnel to the Sun Star casting for removal of its aforementioned transmission and drive shaft floor hump led nowhere, hence the reluctant decision was made to scratch build the floor pan as viewed from above.  If the original tool yielded such detail as manifest as nuanced and accurate contour I'd not replace it soon, although in point of fact what was provided isn't much more than a flat plate.  Although dejected to forced to employ it and puzzled if you will as to what can be done to add some character to this flat thing, there seemed very little reason to clutch to what wasn't working. 

Other factors influence the decision.  The engine and transmission assembly is set back about an inch from standard on the 1:1 topic, while the transmission overrides the transmission crossmember.  Especially as viewed with the hood open, the whole engine and transmission is nearly level as installed and in modest contrast to the usual dip from front to rear.  Given that this racing vehicle is substantially lowered, the differential is higher too, while less angularity between it and the tailshaft of the transmission is of course welcomed.   Yes - it seems they knew what they were doing!  Small matters of detail that may be noted are slightly repositioned hood art (to be photographed and kept in reserve for guidance as to placement post paint application and polish), as well as a front track reduction and recycled GMP Trans-Am tires sans lettering given any decal application will surely be ruined for handling at this stage and point.  Yes - it goes on...

Thanks everyone for the kind notice,

Consistent with protecting the lower extremities of any would be scale racing driver, I felt I had to replace the cast iron bell housing with a proper scale scattershield. Research revealed a Lakewood scattershield was employed, whereas a web search unearthed images that could be consulted to reproduce much of the exterior contour of the same.  In particular, an image was found (and seen below it is) that allowed for careful replication of the outline of the mounting flange to the engine block proper.  Some final shaping is required where the clutch is actuated for this detail still seems a bit heavy, but far from a terrible start.  Fine attachment hardware to come then...

Also seen below is the rather strange homebrewed dry sump system oil pan employed by Team Trans/Action in '71.  A stock pump was employed, but so too an additional pump driven off of the flywheel hidden out of sight.  The stock wet sump was reduced in volume reflecting experiments made in 1970 by Titus/Godsall Racing with 180 degree headers that required certain clearance below for joining the pipes from alternate cylinder banks, whereas indeed upon first inspection the 'short sump' is a bit startling to peruse.  The oil reservoir was hidden within the firewall, whereas I suspect the whole operation of the same would have been kept secret but for the SCCA's decision to allow the use of dry sump systems looking into the 1971 season.  I've hacked down my standard wet sump in the hope of recreating what again is seen in the photo I've included.

Lastly, an interior bulkhead formerly created from sheet plastic has been replaced with an aluminum panel reflecting what material was actually employed in 1:1.  In addition to shrinking the overall dimensions of the home brewed seat the team fabricated for use in this application, I have sufficient confidence in my use of sheet aluminum to rebuild it in metal - so, a coming attraction of a sort.  Harness pick up points are seen on the rear package shelf, hence the odd appearance of hardware so-sited.  Kind thanks for your attention.

Mike K.

...the abbreviated wet sump in 1:1, with a tiny glimpse of the scattershield also spied.

...Lakewood scattershield 1:1 reference employed to reproduce the mounting flange outline in particular.

...rear three-quarter view of the new scattershield.  Note clutch fork opening as well as the starter motor bubble or bump.

...side view depicting abbreviated wet sump.

...bottom view, reflecting plastic plug work, the addition of a tiny harmonic balancer as well as further perspective afforded with regards to the sump modifications.  Note too efforts to clean up the transmission prior to casting the same.  Most parts on view here will also be employed upon my forthcoming Jerry Titus 1970 Trans-Am Firebird.

...the replacement rear bulkhead is seen.  Across the length of the passenger's side floor is witnessed what is intended to be a fiberglass rust repair overlay, with the two diagonally set holes intended as access points for the hardware that holds the exhaust dumps in place situated just below.  The overlay is soon to be covered with Tamiya hobby tape with the intent of lending the panel a bit of needed texture.  Lastly, the rectangular cut reflects what was likely a thermos mount, although evidence of what might have been placed here is effectively nonexistent.

Thanks Jon for the kind interest and especially the spread of recent Donohue Camaro images seen above!  


A considerable pet peeve harbored by this modifier is the reality of tire licensing deals that too often translate into period scale rubber bearing all too contemporary fonts.  Firestone shod racers arenít entirely immune, although in the case of many a Goodyear-shod racer, the too-visible-by-half lean to the right in particular undercuts whatever period-correct illusion one would otherwise clutch to.  The Hall of Shame of those models plagued with somewhat silly footwear includes the Exoto Porsche 917ís, the 1:12th Minichamps Maserati Birdcage, while readers here could doubtlessly identify other egregious misfires of conception and execution.   One could say much the same for 1:1 vintage racing topics besides, where old molds are reemployed to create new examples of old designs though the stark declarative sidewall lettering of days past somehow gets lost in the shuffle.  Not good, and something that could be improved upon looking forward.

For the 1:18th Gray Ghost Iíve been clutching to a single photo depicting the vehicle on a trailer at Bryar, NH. in í71 with the car wearing the larger declarative ĎT.V. tiresí more akin to what had become de rigueur in Winston Cup/NASCAR circles.  The car just looked so sinister, although in truth I hadnít a single on-track shot of the car so-fitted with the larger-lettered Goodyear Blue Streak Sports Car Specials.  In point of fact many races seem to show the car sans any sidewall identification Ė odd this.  

Returning then to the topic of scale Blue Streaks, the blue ring tires pretty much vanished from the tracks late the season the year before, although smaller lettering was long a feature of Goodyear road racing rubber; i.e. people know and expect to see it.  Eventually the sidewall raise white letters seen on the Blue Streak Sports Car Specials had their aesthetic corollary in the ubiquitous Polyglas GT tires installed upon nearly every Detroit enthusiast vehicle of the period.  In short, I canít deny that the usual fitment on the Gray Ghost called out for the less prominent font, set straight and definitely less blue rings.  

Although not perfect, what is seen below constitutes a stab at a solution.  1:18th options for what I desire are scant, whereas negotiations with a prominent online supplier to revise and/or correct his product went nowhere.  Anyhow, the experiment seen below was performed with a 1:25th Slixx drag racing tire decal set which includes rear slick sidewall tire manufacturer identification decals that are larger than the usual scale offerings.  Too tightly spaced to really afford me what I want, each letter was cut out separately and positioned independently on this test tire positioned just to the left of rear wheel arch in the photo.  And yes - I'm still torn as to whether I should apply the gray/violet barrier coat or a semi-gloss black finish to the wheels for this first-half of the season car.  At present I'm thinking this will be a Bryar, NH entry.  

My fingers go numb when I think of the labor involved in converting perhaps nine models over to these markings, but the improvement is undeniable.  The GMP Goodyear font employed on their period Trans-Am tires isnít terrible, although it is scarcely visible for having been rendered too small.  Iím thinking then; i.e. do I really want or need to convert everything over in a single go?  Quite nice even sans clear coat work to eliminate the usual carrier film ugliness.  Thanks...

Mike K.

P.S.  Apparently a 1:25th scale Fred Cady decal sheet for period Jaguar and British Leyland topics of note will supply the needed Quaker State script.  An old Quaker State flag decal image was also sourced for searching out and about and is also seen below.  I wasn't having much fun in my quest to identify appropriately tall lettering, and here express relief that in sum such wasn't that hard to come up with.  Three sizes to play with on the old Cady Designs sheet, whereas here and there one will still detect the care he exercised upon his products; i.e. the flag decal is pretty much a waste, albeit the stand alone lettering is quite good.  Many scale replicas of period racers fall down for rushing the accessory artwork; i.e. the stuff is poorly registered, off-color, and of incorrect scale.  This project should be better in sum - thanks for reading!

...a brief update this,

Another evolution/iteration of the instrument cluster for essentially starting again with a new panel is seen below, whereas scale Dymo labels as well as turned aluminum toggle switches might further be added.  Sorry for the fuzzy photo image - look away quickly lest a headache form!  

The second image reveals efforts to search for appropriate fonts for what in time will be the artwork for the livery.  Given this will constitute my first effort to create decals for something of my own, good it is that most elements present require only a black outline as contrasted to the difficulties posed by other topics and other comparatively complex liveries. Here I take a stab and all that I've seen on the car less hood artwork across the entire '71 season.  The 'Tempest by Trans/Action' identification appeared mid-season and is almost never visible in photos, whereas hints of driver identification on the roof is seen here and there and is clearly not reproduced below.  Lastly, my 'Quaker State' typeface options thus far are clearly substandard, whereas better numeral art is coming; i.e. taller and slightly better shaped too.  Not terrible though...

Greetings and thanks for the kind notice...

A unappealing fact one encounters for converting a stock production diecast model into an stripped down production-based racer is the oftentimes less than appealing surface contours left behind for cutting out panel work and trim.  What seems to be developing into a fair scale replica takes a step back for revealing the origins of this material and that manufacturing process.  The most basic modification will surely include the fabrication of the rear bulkhead and the roll cage, but here I try to add a bit of interest to the floor contour proper. Smaller additions in the form of half-round stock laid laterally across the driveshaft tunnel as well as drain plug holes and stiffening indentations might also be tried.

Iíve found a reasoned way to cheat with regards to capturing the shape of this strengthening member and that short of having the latest and greatest 3D scanning technology and/or printer at my side. In essence I searched online for replacement sheet metal for the panel work I found of interest, blew up the same to 1:18th (approximated), cut the outline of a lateral strengthening member out, and finally glued the same to a stack of sheet plastic layers four deep across with three additional small panels stacked atop the driveshaft hump. Further guidance and support was afforded by searching for 1964 Tempest Ďdry rust free shellí or some such across another Internet image query. The remainder of work performed here consists of sculpting until the addition proves worthy of the billing (i.e. more on this to come). Not terrible then, whereas further additions to the floor will surely be less labor-intensive.  Yes, further floor structure and shape is slated to come. Thanks...

An initial stab at creating a reasoned sheet aluminum instrument cluster bears fruit.  Aluminum sheet can be cut by hand - as long as one doesn't harbor ambitions to use the distorted and twisted material closest to the initial cut for the final panel proper.  About 35-38 tiny taped square stencils/masks were created and employed upon the more or less convincing test panel seen below the dashboard assembly.  Using a Dremel Mototool w/wire brush attachment had its practical limits given I seemed only to be polishing the surface and/or distorting the underlying metal, whereas simply manipulating the attachment by hand and maintaining careful notes as when to alternate strokes and where was in sum all that was required.  A ring of aluminum tubing is seen just before the steering wheel and will be employed as the tachometer lense lip, whereas the photoetched rings seen just to the right will be employed for the minor gauges.  Clear lacquer will be used a 'glue' all the rings in position given that Super Glue  will off-gas and fog (and hence wreck) the fabricated panel if I dare employ it.  Unseen are the holes drilled on the dashboard proper indicating where decorative trim was removed.  Not terrible then...

Thanks Jon,

Some items on the model will be used to form patterns on other material prior to finishing and fitting the same, with the dash cluster chief among these.  I'm hoping to cut or trim some reasonably thin hobby aluminum sheet for the cluster overlay, while for carefully drawing out the checkered pattern and further consultation with regards to photos, mask out and paint over the resultant panel with some appropriately frosted aluminum shade.  It's nice to finally focus on smaller matters versus endlessly mulling how I'll not be able to achieve some satisfying final result without the right rolling stock, the right flare contour reproduction or an appropriately fitted cage. 

...and now for some vintage Trans-Am History Detectives (ala the PBS series mind you)

Although perhaps to be followed up upon with a neat story/photo feature, a fun local discovery was made in relation to the G.G. days ago.  There exist various local sites that have historical interest to the vintage SCCA Trans-Am crowd here across SE Michigan, whereas the most well known might be the original buildings that constitute the Kar Kraft facilities in nearby Brighton, MI.  Of course, if one is sensitive to where the factory Trans-Am Mustangs were first fabricated, this is an important site and worthy of a pilgrimage if you will.  Anyhow, some curiosity existed within myself to seek out the residential property depicted in the period Motor Trend article where the Gray Ghost is being serviced/overhauled between race dates.  Just some suburban split-level in the middle of who knows where, children's bikes scattered about on the lawn up front, etc., while in total the very epitome of a low-buck effort/factory engineers on holiday.  Perhaps not the gates of Ferrari in Modena this, but given what I'm doing, significant enough.  Ownership of the topic on the part of this enthusiast? Check! 

Anyhow, closely reviewing odd copies Competition Press and AUTOWEEK (sorry to shout!) from late '71 I came across a classified advertisement relating that sponsorship would preclude fielding of the west coast races by Team Trans-Action, and that immediately after the MIS contest the Gray Ghost would be available for sale.  A Waterford, MI. address was afforded, while a small photo and telephone number rounded out the ad.  Hmm - was this the old Herb Adams residence, and might this be the property seen in the aforementioned Motor Trend feature story?  A quick visit to the library and research on the property revealed that address particulars had evolved and shifted (town and postal code in particular), whereas apparently the house itself was constructed in 1968 - so far, so good...

Wishing to respect the privacy of others and definitely not intending to telegraph as some confirmed Certified Web Creep, I nevertheless generated some typically scattered and all-but-incoherent MapQuest directions to the property under analysis - this approximately an hour away from where I'm based.  Fun it was to discover an address approximately half a mile away from Waterford Hills Road Racing proper - one could almost (almost) scurry a racing vehicle with open exhaust to the track sans trailer if the dare or wager was sufficient to prompt an attempt, whereas for allowing for the foliage growth, revisions to the property, etc., here indeed was the place.  Within the MT feature photograph the outline and pattern of the chimney seems to constitute the most obvious marker, while this matched exactly... 

Determined not to make a human spectacle of myself, scare children, etc. I did not linger long, although I do believe it would be worth it to compile a small packet of material to afford the current owner insight into some otherwise obscure history while also politely asking permission to reproduce the image, this to be done on some otherwise quiet Waterford Hills race weekend with my model set upon a platform in the foreground.  No strictly high hopes maintained if you will, but hopefully they'd recognize the request as being good natured and construe cooperation as harmless enough.  We'll see then...

Thanks for your continued interest,

Indeed - an odd cage configuration.  Perhaps Donohue's mulling about how it would seem a torsionally flexible chassis can perform wonders in the rain (and as mentioned within the space of The Unfair Advantage) is rooted in a faint remembrance of this effort?  

Seen below is the dashboard in place, as well as the seat mount fabricated from sheet plastic and brass wire.  The fiberglass sheet used to plug up corrosion in evidence on the passenger's side floorpan has been roughly created, while the obviously funky angle the pedal assemblies needs to be seen to.  Now the track appears a bit wide front and rear (to be shrunk a bit then), whereas adding a bit of negative camber to the rear suspension will come with the fitting of a better differential assembly complete with the camber adjusting flanges employed for each side.  The fuel inlet is too small, and is slated to be enlarged, etc.  Kind thanks...

A more substantive update of the 1:18 Sun Star-based 1964 Pontiac Tempest/1971 SCCA Trans-Am season Gray Ghost this time Ďround.  Glacial pace, yes Ė but hey Ė this isnít just a few parts added plus livery.  

Here a complete roll cage has been fabricated, though fairly simple of shape as can be noted.  An odd design to the extent that no tubes extend rearward past the main hoop.  For careful inspection one might also discern that a rear package shelf has been added complete with shoulder harness pick up points (two), the interior trim panels have been substantially trimmed and narrowed (i.e. necessary to afford clearance for the extent of the roll cage, whereas the dashboard still requires fitting), while GMP Trans-Am Camaro disc brakes have been added complete with dust cap (1:25 oil breathers) and axle end detail (GM-specific and scratch built).  Looking a bit meek in the style of early spot/single piston caliper/solid discs, Iíve doubled them up (these having been reproduced in resin) and hope soon to add ventilation detail for use of a tiny rectangular section file.  Proper caliper mounts and calipers to come.  Track has been increased front and rear for adjustment facilitated for the redesign of how everything is mounted.  A 1:18 Lane B.O.P. (Buick/Oldsmobile/Pontiac) differential housing is poised to be clayed up in anticipation of fitting the same to the chassis.  At this point precious little has been done underneath but for a fuel cell housing, hence much to do there.

The bend upward of the cross bar situated just back of the front windshield is reproduced in a manner slightly less pronounced than what is seen on the 1:1 ĎGhost, although this reflects the fact that Iím working with plastic castings versus scale-thinness stampings and such must be accommodated.  Given that the roof must be slightly smashed down even absent the roll cage to properly fit into place along the firewall, know that the dimensions tighten up further when modest pressure is applied forward.  The bars penetrating the floorboards forward will eventually be mated to the frame members consistent with tying the structure together entire.  Know too that the shifter housing/platform is indeed offset a bit  if not bent a bit (versus prim and mounted strictly straight) on the 1:1 racer, the pedal configuration isnít final, whereas the seat rails/mount hasnít yet been fabricated (this being a mock up).  Much floor work Ė especially looking behind the main roll hoop, remains to be done.

All-but-invisible is a new scratch built dual oil filter remote mount situated on the firewall (fifteen parts in total), an odd wet sump oil pan reflecting the choice by Team Trans-Action to recycle select T-G Firebird team parts (here a design used to accommodate 180 degree headers tested in Ď70), as well as revisions done to the fuel cell and fuel delivery system categorically unseen in the trunk.  The seat headrest is now sited with brass rod, while all I had to go on with regards to the configuration of the same is the old Motor Trend image roughly suggesting such.  Lastly, the beginnings of a large Harrison oil cooler to replace the somewhat mousey original GMP Trans-Am Camaro rendition of the same may be viewed resting apart from the model in some photos.  Top and bottom detail needs to be added, whereas the flange/mounting detail is an easy matter to create and yet isnít present within photos.

Fabrication takes time, whereas rendering additions consistent with affording the entire work an organic appearance is a challenge.  Many modifications work best when they canít be strictly detected, whereas configuring a first prototype involves pain.  Kind thanks...

Again, quite a bit of work - albeit largely invisible.  '71 Gray Ghost hood has been laboriously worked over to render its origins invisible - ha! The '64 GTO hood features twin faux hood scoops that had first to be ground down, and then attacked with a sanding block set on edge to comprehensively reduce the remaining 'hills' that formed the raised portion of each, blending the same to the surrounding panel work, etc. A vile task and not for the faint of heart.  Other additions are new resin grilles (cleaner these, better shape, zero warpage, etc.), a new coolant overflow bottle, and rough decal mock up work that, if nothing else, raises my spirits slightly.   

Back to the '70 Titus Firebird - an interior starts to take form.  Much floor detail (contours, stiffening braces stamped-in, etc.) remains to be added.  I must start somewhere though, and hence all the awful cast-in carpeting 'detail' has mercifully been deep-sixed.  No more pedals or pads, whereas a 'consoledectomy' was performed to erase the presence of an undesired detail. Material from a spare chassis was substituted into the hole where the hideous console formerly resided, whereas block sanding again saved matters for it generally looks the business.  A bit too thick of section and too tall though, with the panel work dimensions distorted looking back; i.e. T/G replaced the trans. tunnel body with sheet aluminum rather in the fashion of some gruesome stateside mid-eighties Pro-Stock racer.  A CDI ignition unit is seen forward on the trans tunnel, whereas the rudiments of a roll cage are starting to take form.  Thanks and kind regards...

Nothing profound, but some work to report.  Doubts concerning my ability to create a character line across the top of the shaker hood insert led me to cut up another hood to substitute in material already bearing said character line - a success this.  Seams were visible on the hood run at Laguna Seca, so what is seen here is actually quite good all things considered.  

Continuing on then, the heater core 'bubble' on firewall was removed, a flat plate substituted atop the same space, and an expansion tank fitted w/cap and mount was fabricated and fitted, whereas a pair of GMP Trans-Am Camaro upper control arms have been added reflecting a previous casting effort to capture said detail for reuse.  The upper mounts for the front suspension have been cut off and resited inwards to afford a bit of negative camber - this a near-invisible mod.  

A Lane '68 Firebird alternator has been added, as has the power steering pump found on the same tool.  T/G employed an odd system that provided hydraulic boost for both steering and brakes; i.e. a curiosity this. Lane '68 engine pulleys were cast and cut to reuse the detail on the face of each here atop the stock ERTL pulleys which are crude to say the least.  A '70 GMP GTO Judge will afford this project a radiator, whereas a cast resin GMP Trans-Am Camaro Harrison oil cooler too will be fitted.  The radiators are not seen across the photo images provided, although I do look forward to creating the 'quick change' radiator mount as seen in a single period photo.    

The rear track has been expanded, although no serious work has yet been done on the rear axle assembly which calls for much additional work.  A fuel cell housing, also GMP Trans-Am Camaro-sourced, has been fitted as well as what I took to be tie down points for inspection of the Phillip Larsen image telegraphing such detail.  Some round stock was used for the base of each set against the fuel cell housing proper, whereas the burgundy parts are simply beads that were set in place with glue and with the use of a metal dental pick.  

A new air dam casting was obtained from a friend and more carefully shaped, a set of finned '72 Yat Ming/Road Legends valve covers were cast, cleaned up for oil cap detail erasure (i.e. the sanding down of the caps, and then for dragging a razor saw atop the same detail to match the upraised fin pattern), with the results effectively doubled up to lengthen each to match the cylinder head dimensions. Funny to relate that the effort made on the valve covers will be pulled and simple pressed steel models substituted for I seriously suspect that such is what was run at the first event.  A second mid-season T/G Firebird Trans Am will in time wear these.  Continuing, vents were created on the top of each valve cover looking up and forward, whereas also seen is a washer bottle (square this) that I presume might have been employed as a puke tank or some such.  

Hurst-Airheart hub bearing detail (i.e. shape of the cap) is seen on the rear wheels, whereas the front bearing caps are simply oil breathers reemployed to suggest the shape of the former.  It seems like so little, but a bunch of work in total.  Anything mentioned as cast has generated a mold, hence bits to be added to a product line to come.  Thanks and kind regards to the community...
