I just got out of small bearing brakes for my 1959 nine inch. I had big bearing ends put on.Go bei bearing way less hassel. Small bearing replacement backing plates are hard to find plus I could not find drums for my set up. Mind U my brakes were out of an edsel.I welded morrso perches on mine and used the same pinion angle as my 8 inch.Drive shaft was the same I cant remember if I swapped the rear ujoint or not.I dont think I did.
