I'm looking into making the metal support piece so a friend of mine can get some "dart" pads done with injection molded foam. the cool part is I think it can be done in ABS and modified for either Dart OR Plymouth. It's slow going since I'm going on vactation (the wife ordered it) and I have other projects ahead of that, like the molded glove box and redone speaker kick panels first.
and yes the support metal is different
dart is the rusty one on the bottom.
