Gearing up for my DustDevil restoration.
RE: Wheels. I have a 72 Demon on cop car wheels (15x7). Stockton Wheel advised me that the biggest thing I could get under an unmodified fenderwell was a 235/60-15. Since I had a pair of 255/60s already mounted on the rims, I tried them first. They sat less than ΒΌ inch off the leaf spring in the rear and wouldn't clear the top of the fender opening in front. I've had no problems with the 235s yet.
