Originality / 69 Camaro Rear Wheel Well Plugs
« on: August 10, 2017, 03:30:06 PM »
I'm detailing the rear wheel wheel wells on my 1969 RS Z/28 restoration project ("Brooklyn Z") and was unable to locate disassembly photos of this area. The wwells have received color overspray and now need to be undercoated. I'm conversant with the undercoating process however need to confirm the location and type of plugs originally used in the three, 3/4" holes inside each rear wwell. Quarter panels are original to the car and I recall that my original plugs were a combination of Caplug BP 3/4" recessed style plugs similar to those used on the cowl (2 x 1/2") and on the firewall (single). The other type of plug used was a body plug style plug also found in other locations (floor pan, bottom of trunk drop offs). Below are photos of both types of plugs (web sourced photos). Below also are photos of Eddie M's Cortez X77 Sept 69 Norwood build (mine is a 2B Norwood build) which show only the body plug style plugs used in all 3 rear wwell hole locations. What style (and mix) of plugs were originally used in rear wheel wells?

Restoration / 1969 Z/28 Camaro "472" Intake Manifold Expansion Plug
« on: June 20, 2017, 06:34:45 PM »
The original, steel intake expansion plug from my 472 intake manifold was lost. I sent the intake to a well known restoration shop for re-skinning and was surprised to see the replacement plug they used was stamped with manufacturers' marks.  The original, factory installed 1 1/4" plugs had no marks so what I now have is incorrect. I have been trying to source a correct replacement steel plug and have ordered them from eBay sellers as well as HBC. Despite the item photos they all arrive with some form of manufacturers' stamping marks. I have even tried to grind out the stamp however the result is not suitable for a quality restoration. The original 302 from my Z/28 which is being rebuilt needed a set of replacement frost plugs which I was able to source from a Corvette restoration parts supplier with no manufacturers' stamping marks however I've been unable to locate a correct replacement intake expansion plug. Anyone have a confirmed source for unstamped, 1 1/4" steel intake expansion plugs?

I'm trying to determine the correct finish for the brake hose retainer clips /straps that bolt to the upper control arms on 1969 Camaros with front disc brakes (they may be the same retainers as those used for drum brake applications).  I was unable to locate specific part number(s) for them however they are shown in the AIM UPC J52 A1 Page 359. HBC sells them as flat stock in natural, unplated steel. From what I can determine originals were either phosphated or natural steel. Not painted and not bright plated. From the few examples I have come across they are rarely (badly) rusted which is why I question whether they were installed as untreated. The control arm attaching bolt was zinc manganese phosphated.  Would appreciate your input.

Originality / Correct Spark Plugs for 1969 Z/28
« on: April 03, 2017, 03:28:23 PM »
There has been much written on the the subject of spark plugs for a 1969 z/28.  The original AC 43R's are too cold and 45S are preferred by some (as are NGK, Autolite 86,Champion RJ14YC, and others) however which version of the R43's are born-with correct, the R43N with ACNITER script and 4 equal width green bands on the ceramic insulator

For those of us interested in Bow Tie Class , Legends Concours Class or MCACN and other technical judged events, there is currently no CRG discussion group / forum dedicated to the process of planning, preparation or the general discussion of this important subject. Those CRG members who have been through the judging process will often "debrief" their experience in one or another discussion group / forum however its a hit or miss where the discussion will occur. The current discussion group on Originality is very good and sometimes serves as a proxy for this subject area (case in point, a CRG member who received a deduction for an incorrect battery tray during MCACN judging in November 16 posted a thread on the subject that attracted 41 Replies and 1866 Views) however sometimes what is born-with or NOS correct/original and what is acceptable for judged are different (paint finishes for example). For those of us who are interested in the judging process and would like to learn and share information I'd like to see a new, dedicated CRG discussion group / forum on this subject. Thoughts?

Restoration / 1969 Camaro Rear Bumper Guard Hardware
« on: December 19, 2016, 06:09:35 PM »
I'm trying to confirm the finish / plating used on the 1969 Camaro (full) rear bumper guard upper and lower hardware. The upper hardware consists of a single bolt and hook. From the photo below (Skip's 1969 Norwood 9D 22,000 mile Z/28 survivor), it's not clear if the hook (semi-circle N) was either silver cadmium plated or natural steel? The attaching bolt and lock washer (RSC head marking) appears to have the same patina so it was likely the same finish /natural ? The lower bolt and captured washer appears to be manganese (dark) phosphated

Originality / 1969 Z/28 40669 Fuel Pump - Correct Plating
« on: October 04, 2016, 03:19:14 PM »
In the process of engine disassembly I removed the original 40669 crimped style fuel pump from my February 1969 dated DZ motor.  The fuel pump is dated AI or January 1969 and from the inlet threads it appears the crimp on bowl was originally gold cad plated. I am wondering if any original 40669 pumps were plated using silver cad/zinc? I have seen restored and NOS versions with gold or silver cad plated bowls however was silver cad ever used on original 40669 pumps in 1969?

Was asking about the correct finish on coil springs however I see there is another, recent thread on this.

I am trying to source a 105DD deep groove power steering pulley for my 1969 Z/28 project and was offered the one in the following photos.  I would appreciate input on whether it's an original or repop:

Originality / 1969 Deluxe Hamill Seat Belts
« on: October 29, 2015, 08:06:52 PM »
I need to assemble a set of deluxe seat belts for my 1969 Z/28 2B build (Norwood) project.  The CRG research on this subject is comprehensive however information regarding some details is not (yet) available. The 1969 Hamill deluxe seat belts included what appears to be production reference stamps, alpha-numeric, on the reverse side of some belt buckles, on the floor mounted anchors and on the belt clip (D-rings). There is no indication that these are readily decipherable date, model or version codes. On the D-rings the stamp appears either on the flat area below the latch hole or on the cross bar behind the belt webbing. From what I have read these stamps were not all matched, rather each part (anchor, buckle, D-ring) had a different stamp. I would appreciate input on the following questions from information on original 1969 Hamill belts:   

1. Were all D-ring stamps all the same for each car, all buckle stamps the same, all floor anchor bracket stamps the same?
2. Did the D-ring stamps normally appear on the flat of the buckle below the latch hole or on the cross bar behind the belt webbing?
3. Did the Hamill name stamp on the reverse of the buckle appear above the webbing or below the webbing (just above the bottom edge of the buckle)?

Originality / 1969 Original Power Steering Coupler / Rag Joint?
« on: October 15, 2015, 03:27:49 AM »
Having a debate over which is the correct power steering coupler for a 1969 Camaro - would appreciate if someone would please post a photo. Does it have an overrider bracket or a thicker cast yoke and no bracket?

Restoration / Jack - Ratcheting Assembly Removal
« on: September 02, 2015, 09:43:11 PM »
I need to disassemble the jack in order to properly restore each component part.  The ratcheting assembly is prevented from sliding off the mast by a spur (see photo) that exists on both ends of the mast. Is there a way to remove and replace the ratcheting assembly while preserving or re-creating the mast spur?

The 1969 RS parking lamp lens with the stainless trim ring was discontinued some time in the early 1969 production year. From what I have read this change may have occurred in December, 1968. The service replacement example in the photo is missing the argent paint trim around the inside vertical perimeter of the lens which was found on assembly line originals. As with other early production parts despite specification changes some continued in assembly line use until parts inventories were exhausted. A good example of this was the "shorty" trunk spoiler which despite being discontinued in December/January was installed on some February (and later?) cars. I am trying to determine the latest date these bright trim RS parking lamps were used in assembly line production at Norwood or Van Nuys?
