Okay guys, I'm specifically dealing with a '78 Regal here, but hopefully someone can help. I'm removing the vinyl top, and need info on the trim. 1. Is the rear window-surround trim different between the vinyl top and non-vinyl top cars? 2. (The harder one) Does anyone have access to the part numbers for the drip rail trim for a non-vinyl top car? I found a guy selling an NOS piece for a '78 Cutlass, and I think they're the same, but would like to double check. Or if that doesn't work, talk to some friends at dealerships and see if they can scare anything up. I just can't seem to find any good used pieces for her. Much appreciated.
