I had the rotors drilled to 5 on 5 1/2 and had the center cut larger for the 86 Dana's flange. I used new studs off a Jeep TJ with disc brakes.
I ground down the axle shaft so the rotor would fit over. this is before the backing plate went on. So I know that works. but now that everything is bolted up the rotor will not go on all the way. and I used ther tera flex spacers. So I'm at a stand still.
