Need to convert 72 Nova rotors to Mopar bolt Pattern

[Bossta]

My 14 yr. old son and I have been building a 54 Studebaker Champion to be a ratrod which can also be used for track days. We've welded on a Nova sub-frame and am running a Chrysler 383/727 with an 8 3/4.

We are on a tight budget and need to convert to brake rotors from 5 x 4 3/4 to 5 x 4 1/2 bolt pattern. This is my first choice unless changing axles are cheaper but it needs new rotors anyway.

Any ideas are greatly appreciated?
