Happy Holidays to All.

P.S. I like that photo. It reminds me of a display of Humor in the PNW by AMTRAK maintenance service employees. One year I took a photo of the Lead Locomotive on the Northbound Cascades passenger train at a station stop in Centralia,  Wa.  on the grimy nose of the lead unit (F40PH) the workers had traced a outline of Good Ole’ St. Nick as if he was met face first on the pointy end of the train- Splat!

Only the drawing specs mentioned earlier would denote what was required and executed at manufacture of the OEM Parts.

We (@ Puget Sound Naval Shipyard) have (Mil-spec) plated parts for Naval vessels since they installed the First Golden Rivet ,,, The plating shop used Cad as the primary conversion coating until the advent of the AirQuaility & Employee protections and started using Zinc (Inferior) in the 80's. (note the years  i.e. Cad was primary in the 60’s) They can appear cosmetically similar and variables during prep-applic-finish vary as much as making a Micro-Brew. So results will vary. One commonality is age, IT is a sacrificial coating and like a new borns skin the toll of time is manifested in changing appearance. For example you can 'Burn' the plating with ex excessive amperage, duration & solution make up. These affect the Hue & gloss and color. It is easier if you think of plating as equal to painting & the rainbow of outcomes given the variables,,,,,Your best references are poor quality (Not every one shot KodaChrome) day ½ photos and the interior surfaces that have been denied exposure that are the best source of coating appearance.

Orig Poster: Hold out for the Best,a Orig or the BEST repop that becomes avail. you can afford if you car is a Keeper. If your car is a custom or do not care about appearance options are out there, & I was not impressed with a buddies purchase of current repop from a big box vendor.

FWIW I have two Cars,,w/ restored Boosters,,,, 1 West Coast Version & 1 East Coast Version  and have recommended both directions.
I love plating & have tried the Caswell kits, Local closed (Superfund sites now) plate shops, Farmout (Restoration vendors) and Boeing contract plate shops with varying degrees of success. If anything we have over restored these vehicles to points beyond the orig manufactures standards.
Enjoy your car / project

You can also use #10 x 1/2" flat-head machine screws in the holes in the exhaust manifolds (after knocking out the stainless tubes) instead of having plugs custom-made; the air manifold tube nuts then tighten down to the same dimension as if the tubes were still installed.

Ya, I have even heard of folks suggesting (I would not) installing roofing nails to block the passage. Not very durable in my opinion.

I removed the tube, extensions. Machined (On a Lathe I have) a tight tolerance -plug- with shaping to really seal it up good. The "head" height was calculated to acquire the same standoff distance on the smog air manifold tree tube nuts. It was fun making CHIPS! The plugs do not intrude into the exhaust manifold chamber area at all.

I just went thru something similar.
One of the A.I.R Trees rotted out from the inside and required replacement.
Twisted off two of the 4 nuts and had to machine out the thread (Nut) while not intruding i.e. damaging the manifold.
I used a series of drill bits up to the correct tap size and pulled the 'treads' of the nut out of the manifold holes,,,
then purchased (appx 40$ ouch) a 1/4-18 NPSF 4FLT STR D/S Pipe tap from Fastenal (pn 16356 Brand Greenfield Tap & Die) and chased my manifold thread for a clean fit on the new tube nuts.

P.S. also machined some custom hidden plugs that seat below the tubes as my pump is de-vaned and need to seal exhaust gases from the check vlv etc.

My 68 396/325 w/ smog has the orig line and it is JAMMED in btwn the block-cover & smog pump mounting bracket.
Amazing how tight it all is. Lots of contact. 80K mile LOS car Coded "MY"
Makes hooking up the carb a hassle and must start the threads while carb is not on studs to get the angle correct.
I have not adjusted the valves in a while but think the vlv-cover is a bear to get removed.
There must be some slack to tweak the line as needed to get things attached.

159  Camaro Research Group Discussion / Originality / Re: Follow up to topic of floor plan plug on '69's on: March 25, 2010, 10:20:59 PM
Dave, I kind of cheated when I fluffed the underside. The dealer undercoating was SO thick I chipped-scraped it off the plugs the plating was preserved and the orig sealer held the plug perfectly that I just touched up the orig sealer with a bead of fast-n-firm. I could see some evidense of stamping but very hard to decern the text. Due to the fact I did the underbody fluff as the last item to refurb I did not  remove them for better documentation-examination and can not offer much details. I will say the  (LOS) underbody was black with lots of factory white (50-A) overspray on the underbelly pan, frame rails & trunk pan.

160  Camaro Research Group Discussion / Originality / Re: Follow up to topic of floor plan plug on '69's on: March 21, 2010, 11:37:50 PM
I removed the plugs from both of my '69s. A couple of them had date stamps. All of them were indentation up. Can anyone point me to the correct sealer product for re-installation?

I just did the underbody make over on my pace car and I used:
Fast'n Firm
Seam Sealer
(Tube- like caulk gun style)

Sets up hard and is more white-beige Perfect product.

At first glance that looks like what has been on my 68 396/325 since I purchased it in 1983,,,,,,
