YH wheels entered production January 1969.

I have one for a '69 Camaro and it looks like new. Also have other paperwork from the same dealer.

Last fall I saw an original Gutenberg bible, 558 years old. Probably wasn't always well stored but still looked pretty good. Kept dry and indoors, paper does just fine.

Body and chassis broadcast copies often remained in completed cars shipped from the plant. They were usually discarded during new car prep. However a few dealers put them in the glove box or in the folder of paperwork retained by the dealer. That may be what occurred here as yours looks genuine.

Wow!

Great work getting it pulled guys!

This ebay ad prominently mentions documents and features several photos of them. The alleged ‘original’ documents have several inconsistencies with genuine original 1969 Camaro documentation.

Exception Control Letters [ECL] are the two-character alpha codes listed after the option; A01 is tinted glass, AA is the ECL for the specific build. ECLs are application-specific; there are at least 22 for Z22. 5 of the ECLs on the documents for this car are inconsistent with others in the database. In addition there are two spelling errors and an error in the listing of the options.

The ad states: “The window sticker and shipper sheet reflect…and the D80 rear [?] spoiler option” however air spoiler equipment is not listed on the paperwork, such as it is. The car has C08 Vinyl Roof Cover and Z21 Style Trim Group, also not listed on the purported original documents. The ad claims a stereo radio but the documents list the U69 monaural am/fm.

There are several incorrect or missing components evident in the photos: headers, no AIR system, master cylinder, trunk mat, stripe color, ducted hood.

The ad boasts “Send your inspector today!” I second that motion.

Check out a more modern ZL1 dyno test on the engine from #26:

http://www.camaros.org/copo.shtml

With today's 0 weight racing oils and the latest piston ring technology Camaro Hi-Performance is seeing 550hp+ on their ZL1 rebuilds.

The only 430 hp engine of the timeframe was the L88, only placed by Chevrolet in Corvettes, and it did not use an air cleaner decal.. as the 'hood itself' was the top cover for the Air cleaner.. Smiley



The ZL1 was also rated at 430 hp. The few period engine bay photos of ZL1 Camaros show either no air cleaner lid decal or just the 427 crossed flags.
9  Camaro Research Group Discussion / Restoration / Re: NOS Rear shock absorber P1132 on: July 06, 2014, 04:16:11 PM
Camaro SS equipment did include different chassis components, mostly heavier-duty springs. I believe '69 was the 1st year spring selection in production was based on option content/weight. There was an optional F41 Special-Purpose suspension; Chevy was vague as to what that included. However service replacement shock listings mention 'Spec Perf Susp' so that may have been the difference.

Would be nice to have a CBC for an F41 car.
10  Camaro Research Group Discussion / Restoration / Re: NOS Rear shock absorber P1132 on: July 05, 2014, 12:45:11 PM
Parts cars, ebay, swap meets. Very tough to find. Replacement shocks were heavily marketed in the '70s so many OE shocks were quickly replaced. Sometimes worn out but I believe they can be rebuilt. Corvette guys have been doing this for decades. You would not believe what a bud paid for a used set of '65 Corvette F41s dated to his car.

11  Camaro Research Group Discussion / Restoration / Re: NOS Rear shock absorber P1132 on: July 05, 2014, 11:58:31 AM
Service replacement parts are often more generic than OE to cover a broader range of application.

For '69 model year production 2 rear shock absorber codes have been seen on cars built with 12 bolt axles; TN for automatics [3192832] UN for manual transmissions [3192851]. We have seen one anomaly for each code. If GMPD serviced those numbers it wasn't for long; they are not listed in the October '69 P & A manual. The generic service 12 bolt rear shock at that time appears to be 3182033.
12  Camaro Research Group Discussion / General Discussion / Re: Another 99K 69 Z/28 on: June 21, 2014, 11:42:50 AM
was welded in 68 also, why was that ?  Noticed it when I pulled my exhaust out of storage for pics. ( sloppy weld job BTY)


Beautiful car

Don't know why I was thinking wide ovals ,no coffee in me at the time.

Welded because in production it establishes positioning and it's one less part that needs to be fastened. Might not sound like much but at 57 units per hour it adds up.

On the N10 standard system the head pipes were also welded to the resonators but I believe that was an MVSS requirement. Something else that recently came to light is the original production configuration of the "bright metal" tailpipes. The LH tailpipe was the standard 1-pc pipe; the end of it polished raw steel/flash chromed. The RH pipe was 2 pc welded construction with the tip nickel/chrome. Several original systems still exist in this form.

Remember all this if you see a complete NOS exhaust system for big $. Might be NOS but service replacement components were not identical to parts used in production.
13  Camaro Research Group Discussion / General Discussion / Re: Another 99K 69 Z/28 on: June 21, 2014, 08:54:16 AM
The tailpipes are not adjusted properly. The factory spec was 0.64" from the top of the pipe to the base of the rear body panel. The system used in production had the RH tail pipe welded to the muffler. It was not welded on service replacement systems. Also, should have resonators and too early for chromed tailpipes.

Production E70 x 15 tires for Z/28 and COPO 9737 were Goodyear Wide Tread GT or Firestone Sport Car 200.
14  Camaro Research Group Discussion / General Discussion / Re: July 1969 Norwood shutdown on: May 25, 2014, 04:10:42 PM
The Norwood plant shutdown at the close of business Friday July 11 and resumed production Monday August 11. VINs after approximately N669119 were final-assembled in August.

The NCRS dates I'm seeing don't exactly match up to the last VIN produced for the month records from Chevrolet. Depends on how it was defined for shipping/invoicing purposes.

As an organization the CRG does not render opinions on specific cars. Our members may voice an opinion as individuals, still a free country last I checked.
