70 COPO..Thanks. I understand but in terms of a basic explanation of the fleet codes in general..Was it a code for when GM would built multiple same optioned cars/trucks? and if so then why would my car not have one being such an " in the thick of it" o4A festival car? And why would so many LA non pacecar cars have these codes at all? Did dealers out that way save money by ordering multiples of the exact same car for themselves?
