for the record there is a 5 lug disc brake kit for sale but it is for a 49-50 1/2 ton. The axle in my 52 3/4 ton is a 52 1/2 axle. Would the bearings be the only difference between the kits for 52-59? If so anyone have the specs. I could easily get the correct bearings at a local bearings & drives shop.
