If you have an original '63 12 bolt, you can not bolt on any rear disc brackets. The '63 had backing plates pressed onto the axle tubes. So there is no flange to bolt any brackets to. If you want rear discs, you will have to weld some caliper brackets onto the axle tube. The bolt on backing plates started in '64.
