New rims and tires on a 64 Barracuda.

Forgot a few other details. Had a 7 1-4 rear. Upgraded to 8 3/4. ESPO 6 leaf leaf springs. Stock location. Don’t know if someone makes say 4 1/2” back space 15” rim. There’s about a inch of space on the inside by the leaf spring and about an half inch on the outside of the tire by the inner fender well. And there’s no weight in the car. Fuel tank is empty. I just bounced the car using the bumper and the outside of the tires clear the inner fender well. Won’t really know till I get it on the road.
