Hey everyone. New to the board, but a long time G body owner. So I have a 1978 Cutlass Cruiser (wagon). It was a 350 from a '72 Cutlass in it. I am looking to put in a new ac/heater system and new wiring, probably a harness from Painless. I am looking at a Hurricane system from Old Air Products. Anyone have any experience with this system or advice?
