Why? you have an original set of hat rims in your picture. If I were you, I'd get them restored and if loaded with Ca Cl get them drained NOW. there are replacement rims available, 6-loop type, that will slap right on. They run about about $110 each. I don't know of any other rim that will fit a Ford, but there may one out there. Truck rims of the era were different and if that's what you seek, good luck. I suspect your hat rims are 28" so if you decide to replace them, let me know as I'd be interested in buying your hat rims.
