I have a 1970 Gran Coupe resto mod with Wilwood disc brakes all around. I have a space saver spare in the trunk that’s really just for looks. I don’t think a standard 15” Mopar wheel will fit with these Wilwood calipers. If anyone is using these calibers what spare wheel did you find to fit?
 
A few years ago, I worked and helped on a wilwood disc conversion on an a-body barracuda, 68 or 69. The 15-incher wheels didn't fit. They had to go with 17-inch stamped steel wheels to fit. That said, the 16-inch may have worked, but 16 has pretty poor tire selection. Looking back, that specific wilwood system was bigger than the car can use, and had we to do over, we would have chosen a disc conversion that fits the 15-inch wheel.
