I need pictures of Darts with 15 x 7 wheels on back!!!!!!

Have you swapped to big bolt pattern? My car with BBP (8-3/4 with 11x2" rear drum and the larger 11.75" discs) wants an 15x8 or 17x8 rim with a 22mm back spacing to center in the rear well. This will clear a 245/45/15 or 17 with about 1/2" per lip and spring, and mine are rolled but I have unrolled wheel well trim. The front wants more positive offset and/or smaller width tire and/or narrower rim. I currently run Centerline Convo Pro at 15x7.5 and a 225/60/15 tire, with a 5" offset. For some reason the 225 I have are as wide as 245 at the bulge.

If you have deviated from stock the best way to know is measure your car. I have one side of my car that is bit different due to a quarter panel replacement.

Oh and 1970 and newer Darts, Dusters and Dart Sports have different fender well sizes.
