I actually have a pretty bad dent in my rear bumper. What do you want for it?'67 and '69 should be the same front bumper.
I sold my original '69 front bumper a couple of years ago, but still have my original '69 rear bumper available if you need one. It's correct for both '68 and '69 model years (the '67 rear bumper was different with the backup lights in the bumper).
