Yenko Interview

[Big Chief]

Thanks for the thourough reply. It answers several of my questions ahead of time. Some oddball cars would make perfect sense considering the special order nature of the cars and dealer. Since Yenko offered options such as blow proof bell housings, headers, etc, I knew there would be some differences between cars, but I felt the base COPO cars were all the same and there were no "factory" cosmetic options.
New question - Can you tell me if the COPO cars came with a unique cross member for the 4 speed cars? These cross members had an indention near the transmission mount, I assume to clear the shifter linkage. It also appears the transmission mounting holes are offset towards the driver indicating the engine may have been offset in frame as well. Also, why did the factory feel the need for a specific shifter mount for the round bar shifter on the big block cars as indicated in Rick's 1st Gen Camaro catalog?
