I've done some internet searching, and I can't find much. There is a 75 "Cutlass wagon" near me that I'm fighting on whether or not I want to go get it. The good is that pretty much everything is there, the bad is that it needs some sheet metal work. Not horrible, I think some body filler might be sufficient to fix it up, but I'd rather do sheet metal if I can. Floors for 74/5 are easy enough to find, but it seems like that is it. I'd also be looking for rear quarters, specifically around the wheel openings. Anyone know a good place for sheet metal for that era of wagons, or at least the 4-doors? The upper area of the quarter on a typical sedan probably has a different profile, but it should be pretty close around the wheel openings if not the same profile.
