I've been searching, this is what i'm going to do, Front The Hollister Road Company Disc Brake Conversion was designed to be used on 3600 and 3800 Chevrolet Truck from 1947 to 1959 with single rear wheels. There is a difference between front wheel hubs on single rear wheel and dual rear wheel trucks and both can be 8 lug. Rear I'm getting a 73-87 14 bolt FF And putting the Great lakes Offroad LLC GM 14 Bolt Full Disk Brake Kit w/ E-Brake Calipers. and a late model GM master and Booster. I've decided to do all this because can't get rear parts for 48 3600.
