I ordered both front and rear disc brake kits for my 1952 F-1 pickup the front kit would fit, but the rear kit did not have a large enough bolt circle to fit my axles. I kept the master cylinder and power brake unit and sent the rest of the order back. I decided to stay with drum brakes. The tech dept. tried to find parts that would work but none were available for rear disc brakes with a 5 1/2 bolt pattern.
