It's the 1967 Auto Show, the Z28 seen in the pictures has the '67 front end as well as no side marker lights. If it did have an 06B build then maybe this picture proves that the rumor that there might have been two of these show cars built?

In it the restorer explains that it was originally a white car.

What I'm most interested in is finding info for the Californian Camaro.
