1989 ZR-1 Pilot #004 Thread

[1989ZR1#74]

John, What was the criteria for assigning an EX#? For example, your snake skinner had a standard VIN: #081 but Snake skinner II had EX6153? Thanks Eric

004 (DRM/Saddle w/saddle seat backs)
at least 4 that went to Europe (Car labeled #6 DRM/Saddle w/black seat backs)
078 (DRM/Black)

Can you scan the picture? What color is the interior?

The picture is of the back of the car and theres no interior shot.

Vehicles with a VIN usually meant a pilot or production vehicle. The EX number, if applied by the plant meant that it was some kind of prototype. Experimental! These vehicles had to be paid for out of budget immediately and would be used for some kind of testing and presumably would never be sold, but would be scrapped out.
Some VIN vehicles were turned into EX vehicles when enough experimental parts were installed to where the vehicle would become experimental. Discpline on this was not that great though

So Snakeskinner ll was never a pilot but was a prototype. It probably started as a 1987 or 1988 car.

Now that I said that, it could have been a 1989 that was turned into an EX number, but i thought it was an earlier car than that

P9Y066



Using that info I went back to the fragment of #004 build sheet and found this in the order number:



So I think S9YKH1 is its internal number 9 = 89 Y = Corvette,
S = Sales?
KH1= King of the Hill 1?

Any thoguhts? Eric

The P mumber is what GM useed to kep track of these cars. If there is info filed it will be filed under that number.

This is a copy of what was in the frame of mime which means it was on the frame build part of car as it went down the line. When the body was dropped on the frame a worker put the 'extra' sheet in the frame. Eric you can get a copy of the build sheet from the NCM.
On this document you can see all the numbers tied togeather on one page. The ex # and p# in the KOH line and the actual assembly line build on the top right. I have never seen the rpo codes lined out like this except on the 88 prototypes like mine, I can only assume the build computer did not have them programmed as options yet.

The telling number is the frame vin that can then be checked against this.

That will tell you what the car started out as off the production line.

once it was decided not to sell these cars, it certainly did give us the largest group of project cars imaginable. having them did help to make sure the 90s were as good as they could be.

I think P cars were not mutually exclusive. #074 was 9PR110. No "P" nor Y. This car is an "S" I am sure GM had a S group. So it's "P" number is S9YKH1 if that makes any sense. My space on the build sheet does not have the same info yours has. No EX# No P number. THis car belonged to the Chevy Photography/Campbell-Ewald. A whole different group. (which is probably why it is still here. John and his guys seemed to chew up those P numbers. Not to many of those left anymore but at least 5 PR cars are still here.)
