I have a 77 RS and my son just received his rolling chassis 79 Z28 from Fbodywarehouse yesterday. Talk about a happy kid! Anyways, I was wondering what information is available from GM in the form of build sheets on either car? Mine is a Van Nuys car that the sheet above the gas tank is just bits of dust, and my sons Z28 is a Norwood built machine, but its a gutted chassis. Any paperwork stashed away in that car is long gone. Any info is appreciated.
