72 demon core support

tip - look for a 70-72 Dart or Demon lower support - there are 2 little tabs on it to mount the valance. As far as I know, Dusters don' have them - at least my 73 doesn't.

That is correct, same as the little bracket on the trunk pan at the rear. you can always transfer them.

You can replace just the lower half if need be. The yoke is two pieces.
