I had some of the same problems. Truck was stolen and striped from the radiator to the rearend,. including the booster mastercylinder and bracket. Had booster and master cylinder from a 1971 1/2 ton but mine is a 1970 3/4 ton with shoes front and back. First booster for 70 would not work because the ajuster was to short by about 1 1/2 inches, I was able to get a dual diaphram booster 10 1/2 inch that was for a 1971 front disks but shorter in length by two inches and it all went together fine.
