I have a '53 3/4 ton and plan to make it my daily driver. Upgrading the front brakes to disk and front hub bearings to taper roller seems a good idea. I have access to a AD 1/2 ton with disk brakes. The 1/2 ton brackets for the calipers should work on the 3/4 ton spindles--bolt pattern is the same. Trial and error at the parts store will get me the proper rotor to go with the 1/2 ton calipers. Has anyone done this upgrade and know which 8 lug rotor will fit? Same question about fit for front roller bearings to replace the ball bearings. Thanks guys.
