I gathered up parts to do a rear disc but didn't finish it. I pulled the rear set up from caddy front wheel drive cars AS i remember it the center hole on some GM rotors are smaller than the boss on the axle shafts also not all lug studs are the same size I have seen the caddy rears in S 10 set up the key is the center hole must be a tight fit on the axle and the lugbolts must match the rotor hole size, or drill every thing out to use bigger studs
