Help: 72 Dart Swinger front pass. fender rubbing

That fender measurement may be a year change thing. I just measured the '71 Dart fenders on my Duster and they both measure ~8", but a '72 Dart fender I have here measures closer to ~7.5" like yours.

The rear dog legs have a similar changeover, the 72+ fenders are about 1" narrower in the dog leg than the 70/71 Dart fenders are. You might measure the rear dog legs and compare those as well, you may have a one of each type.
Thank you this is exactly the info i was looking for. Sounds like i might have a 70-71 passenger fender. And just to be clear the dog leg is the support bar that goes from the frame to the bottom of the fender lip right?? And lastly, what other models would use this type of fender that would be compatible? Demon? Duster?
