I could be wrong, but I believe the over-riders on the rear bumper are one year only . . . aren't they sloped a little different so the wider decklid will clear? I've got a rear bumper off of a 67 . . . the blade is bent and pitted, but I think the over-riders are good. I think I know where you can get a pretty decent 67 deck lid if you need it, but you might be looking for a while for the one year only apron. It might be cheaper to have yours straighened out.
I know where there was a 67 sitting the weeds a couple of years ago, but I'm pretty sure the apron was trashed. It was hit hard on one end or the other . . . and I'm pretty sure it was the rear. I'll try to locate the guy's name and number and if he's still got it, I'll go take another look at it this weekend just to make sure.
