IIRC, Clair Davis found inexpensive sources for Mustang torque thrust knock off rims that have a larger center register for Mopar center caps?? Clair??
Not found by me, I think it was Rob McCall. The brand is on ePay all the time, but they don't specifically claim to fit anything but Mustangs. I'll see if I can find the brand and info and post it up.
