Door skins would be great because they would work on all 67-76 A bodies.
Trunk extensions are great because now you need to modified Dart extensions. How a bout a good fitting rocker panel. They should also fit all A bodies 67-76
Another goo piece to do (although its not a Barracuda piece) would be Dart Dutchman panels, They are the same again from 67-76 and are comman rust areas on vinyl roof cars.
