Since the kit is based on Cobra brakes, I think you'd be safe with Mustang Bullitt rims. A quick search turned up a variety of 17 & 18" sizes. Probably good with any aftermarket rim that uses the Ford center bore. Or you could leave a step on the hub to center the rotor, and have the remainder of the hub turned down to the Mopar diameter if you really wanted to.
The calipers are Mustang, but the rotors are c4 Corvette, and I don’t know about the hubs. I don’t think they’re Ford. I’ve read that a lot of people have had to machine Mustang rims.
