Awesome, thanks for the info Les. I just talked to Vintage Air and they said that their Gen II Super will work just great with very little or no fabricating; that it will fit perfectly in the 72 Firebird without any problems.
So I'll probably order that next week and have some nice cold air by next weekend!
