10” Rim on rear of stock ‘72 Demon??

SO are you saying a 15x10 rim wit 5.5 BS and a tire that is 28x10.5 wide will fit in an unmodified Demon? Damn y ou for making me get under my car to measure! lol

On a Duster with no spring mods at all, my buddy ran a 15x10 with 5.5" Back space and a 28x10.5 MT et dragslick no rubbing. Demon should be the same . I was going to buy his used tires and wheels, but they were ugly Pro stars so i passed.
