Hello, I have a 1977 Camaro and am swapping an earlier RS front end onto it. Now I'm looking at the rear bumper as I'm nearing time to primer. Does anyone happen to know if a 1970-1973 firebird rear bumper is even in the BALLPARK of being able to seat against the '77 rearend? None in my immediate area to look at, and I've googled and searched on this website and haven't found anything yet. I'd be able to cut it up and weld it, I just don't want to get into english wheel, shot bag territory y'know? Just thought I'd give it a shot in case someone has held one up there before. Thanks!!.
