B-body 8 3/4 axle in a Duster! Photos
since you have a dart, and not the Duster/Demon/Dart Sport you'll probably want it cut. The wheelwells are that different. Standard width rearends look strange in a Duster/Demon/Dart Sport...this is an a-body 8 1/4 with the same wheels on it:
For me, it seems like a 275 tire would fit in there with a 15x8 5.5" backspacing rim. The tire would have about 5/8" to the spring if my calculations are correct and would be about the same on the outside.
