I don't have a solid answer for you on that. My car is a '71 Dart Swinger and through my rebuild I have discovered that many parts from the '70 Darts are interchangeable with the '71 Darts. I also know some of the parts from the Scamp, Darts, and Valiant are interchangeable through each other as well. They are basically the same car with a few cosmetic differences. Sometimes it makes a big difference if the car is a two door or four door too depending upon what you are talking about.
