1972 Dart Swinger Front Fenders

Like stated above, fenders are the same except for the side marker lights. 72 was a one year only fender so it will likely never be reproduced.
Patch in the old marker light hole then make the cutout for the new style marker light. A die grinder and air file makes quick work of it.
Another option is to patch in the old style marker lights on the quarter panel and make it look like a 70-71. Just be aware that the early side markers are hard to find and expensive compared to the cheap 72+ ones.
