actually jayS…the four bolts…are PART of the drum…yes ford IS THAT retarded…the wheel studs are pressed INTO the drum, as in its all one peice, held on ONLY by the large central nut on the spindle. GAY, and also there really ISNT an adjustment hole in the back. only way those shoes are tight enough on that drum is if the ebrake is ON, or the brakes were done VERY recently. if all else fails heat up the drum right at the center around the spindle to break the reaction of it “welding” itself onto the spindle for lack of better words.
