69 Camaro ZL1 Prototypes

[Jeff H]

A rear sway bar? Was that on the black/gold car or one of the other cars at the Tech Center? That's interesting because the GM rear sway bar was designed for the 67 rear which didn't have the staggered shocks. Does anybody know anything about the cars shown in the pictures at the GM proving grounds? The black and gold car is obviously the ZL1 prototype but did it start life as a Z28 and receive the ZL1 transplant? Also, what color were the other cars in the pictures in Marty Schor's book? The one car looks to be either Orange or light blue but it's tough to tell in a black and white picture.
