Thanks guys for all the input. After some thought cooler heads have prevailed and he is going with a Gen III Firebird ('90 1/2- '91). We found one on Craigs List for $200. I cant believe how cheap this stuff is, the fiberglass roadster body was far more. I gave him a rule book to read and reread.
But the questions is as more late model cars are built, this will be something that will certainly come again. Tony
