Hey Mark, I have the one on the '68 tail light housing, and I also have a pair on the rear of a '69 Dart sedan. The passenger side one looks like the worst of the 3. What are they worth to you? Looks like I'll have to pull the rear bumper just to get them out, so if you don't mind a bit of a wait then that's cool.. lol
I don't have any seat medallions like that, sorry.
