Like I said, none for the 73+ cars.
But AMD has a Demon tail panel, which would be basically the same except for the tail lights. So you could either use it to repair yours, or use yours to change the tail lights on the demon panel. Not easy, but I don’t know how rough your panel is or how long you want to look for a good one for a ‘74 Dart Sport.

They also have a ‘72 Duster panel in stock

Looks like the 70/71 Duster tail panel is out of stock.
