57-64 F100 spindles need small pattern rotor

Hoping someone has a suggestion. I have an old sprint car axle with these spindles. I'm wanting to use it in a '63 Nova gasser, but need a rotor with either 4 1/2 or 4 3/4 bolt pattern. Was trying to use a '76 Camaro rotor, had all the bearings and seals worked out, but the spindle is too long to tighten down on the bearings. Hoping to find something that will work with no machine work. I've seen mention of Granada rotors. Anybody??
Thanks, John

 

If you find something in the 4 3/4 bolt pattern that will work let me know. If I decide to run something other than steel wheels the 4 3/4 pattern will give me more options over the 5 1/2
