Thanks for the info. The floor is where the majority of the rust is, so needs done either way.
I have spoken to a fellow near here that has a 46 for sale and it is sitting on a 74 Cutlass frame. He didn't do that part himself, but has been working under it on what he wanted done and he said it was a fairly clean swap. No mods to the frame, fits well and only mounting point mods on the body.
1973 - 77 GM 4 door & station wagons have the 116" wheelbase, but try and find one now that I am looking...but Camaros seem to be all over the place here! Probably because they won't work....go figure.
Anyway, I appreciate all the help and tips from everybody. I am looking into all suguestions and following-up on all ideas, I really appreciate it!
