1968 Dart 270 two door hardtop beltline trim
Here are some pictures:
The piece third from the top is the one in worst shape from the passenger side. Someone with patience could definitely bring it back to daily driver condition.
I forgot I also grabbed a bunch of other interior and exterior trim bits:
Driver's side driprail chrome, rear 1/4 window inside upper panel trim, headliner trim for the perimeter of the ceiling, and anything else you see in that picture. It all goes with the beltline trim. Buy one piece and you get it all.
I don't know if this is the same as the 69 Dart trim. Several trim options were available these years.
