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???
