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
I wonder what the sidewall width was on those slicks , with a 10" rim---------------trying to decide to mini tub or do the same thing. Drag radials ain`t cutting it for me.
