The rear rotors on a Pantera can be replaced with an ORIGINAL 65 Mustang front rotor.
The issue with that is they are obsolete from Ford and the aftermarket has modified them to now include the front bearing hubs.
I think though that if you have a 12" or 14"lathe in the shop, you can machine those hubs off of the rotors.
I don't know where you could get the front from though?
