71 supper,
I am converting to disk up front. Found a 71 junkyard dog that had all new upper/lower ball joints, I/O tie rods, calipers and new five lug rotors. I robbed all, plus the spindles and backing plates. I want to keep the six lug being to costly to buy new 5 lug rims at the moment. Will GMC Pauls rotors fit the 71 stock spindles?

Thanks.
