Did disc brake swap from 60 series axle, pulled all the old drum s***, then rebuilt with 60 series knuckles backing plate, new calipers, 60 series hub, Asian locking hubs, new rotors. Sand blasted all the 60 parts and painted black, then assembled with new bearings, centered the knuckle. The only issue was having to clearance out the ball on the axle for the 60 series birfs, to fit. Used the 45 axles with 60 series birfs
