Where there two ZR-12s????

[1989ZR1#74]

Ok, I have documented earlier that the Conan ZR-12 at the Museum is 1989 Vin #040, P9Y074. The ZR-12 is Bright Red with a GRAY interior:



Well in my neverending quest for information on the 1989s I came accross the July 1992 Issue of Vette magazine:



The magazine identifies the ZR-12 as EX5664, WHile reading the article I was struck by a couple oddities. The car has side pipes and a SADDLE interior:





But the one at the NCM has a Gray interior:



The magazine ZR-12 has sidepipes:



So were there two ZR-12s or did Chevrolet rebuild this, take the side pipes off, and swap out the interior???

There are some pretty sophisticated Headers on the magazine car:



The NCM car has under body exhaust:

Not sure if there are two yet, could be just the gray looking "saddle" in the mag, but there are some big differences they had to make after the 1992 pictures.

Is that overflow tank a prototype unit or production?

The tank is early '89 Z, late '89 Z were black.

To answer everyone's question, there was only one ZR-12 built. It has saddle interior, custom headers, side pipes with modified covers from a '67 Vette. Later, we changed the exhaust to run underneath the car. The real authenticity check will be to look underneath at the U bolts holding the exhaust - the ends of the bolts will be scrubbed down from bottoming out at 130mph at the base of steep hill. And if that doesn't work, I'll use my spare key to start it.

Good stuff to know. I new the VIN from the SPI and the EX number from the tag and then found a copy of the build sheet at the archive that tied the two together. The confusion came from the change between the original version:



Side pipe saddle interior

and the way it sits today at the museum:



No side pipes and grey interior.
