17" versus 14" tires
That's not good information. It depends on the year of the Dart and Demon.
'67-71 Dart fenders pretty much have the same exact clearance to the lower front corner as a Duster does. I have run 275/35/18's on the front of my Duster with both Duster and '71 Dart front fenders, the clearance was pretty much the same for both.
At some point in 1972 the front lower section of the Dart fenders became narrower by about 1", which gives more clearance at the lower front corner than a Duster would have. I don't know exactly when, but I have a '72 Dart fender that has a longer wheel opening than the '71 Dart fenders I'm using on my Duster. The AMD reproductions match the later fenders with the wider opening.
The rear corner of the wheel opening is of course is more limiting on a Duster, but in my experience the front lower corner is the bigger issue. And yeah, that's the same Duster or Dart if the Dart fenders are '67-71 at least.
