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???
