I, had bought new a new hub/rotors, from Napa, and the wheel studs were too short. The studs were bullnose, and it was hard to start mag wheel nuts. The Dorman 610-279 also have a bullnose, and were barely longer. I, used the Dorman 610-363 studs. The rotor, has to be drilled out to 11/16ths, and the hub needs to be drilled out to 5/8ths. In the first picture, the one on the left, is a stock 1978 Bronco stud, a stud from the Napa hub/rotor, the Dorman 610-279, and the one on the right, is the 610-363. The second pictures shows the flat, that needs to ground in the stud's shoulder. The flat is needed, to clear the side the the rotor. The third picture, is the Napa hub/rotor's studs. The fourth picture, are the Dorman 610-363 studs.
