90 ZR1 #102

[1989ZR1#74]

I dug deep into my archives and thought I would post the 1989/1990 Evaluation form GM would have wanted the driver to use at the end of GM Service:

I have attached the build sheet for #102. Thank you Eric for all the valuable and interesting information you have provided. JC

Some other C-P-C "Dealers"

052 CPC Group Milford Proving Grounds
185 GM Service Development Center

#102 was more then likely assigned a "1" p number as a "production" test use car. For example Heinricy's Snake Skinner was assigned

19Y0123
1- Production Pool/general use.
9 = 89
Y = Corvette
0123= 123rd 19Y numbers assigned.

So #102 would have been 10Y0XXX

This number was used for cost accounting and tracking purposes. Car would have been used by CPC until it reached 3000 miles then it could be sold.

There is a slight chance this number is typed on the Build Sheet somewhere.

One more area to check for info is on the actual tank sticker. Many tank stickers have addtional hand written notes on them abouve wht the NCM build sheet has.

Here is a comparison of #004's NCM sheet and what was left of the tank sticker.






I think other then these two longshots the vehicle invoice may provide some addtional info. Ususally it will at least say when it was sold from CPC inventory. Eric

Hello,

I just found the original title for my 1990 #0077 and it says '10Y022

Its actually written on the title under the address

Chevrolet-Pontiac-canada Group
10Y022

Dempsey, your car was a PEP car of some type. 10y is the tip off. It was a production car used for QC or service . Order the build sheet and Invoice. Well worth the $80 investment. Eric

Jingles told me all cars delivered to the tech center coolant systems are checked and the number was written on the fan shroud. To prove I am not "all knowing" I have yet to determine what the number actually means, but I have seen this on virtually all prototypes and engineering units I have witnessed.

Look what I found under the radiator area!!!:







it seems as though my 90 #0077 was built on 222nd day of 89' and delivered to CPC....

As a side note I will upload photos and journal of work on the 90' today

A copy of this form is the same as the one put in the left front suspension. The car was produced on 2 different lines that joined when the body was placed on the suspension. Both lines started with the same build sheet but it seems the one in the chassis line had more comments written on them. When the body was dropped the sheets from the chassis line were discarded/placed on the fuel tank or into suspension. The body sheet stayed with the car and is what the NCM has a copy of.
This is a copy of what was in Queenies suspension.
