yes, change the ball joints and spindles but the tie rods are different for disc brake trucks also, i believe someone sells an adapter sleeve thatll work so all you have to change are the outers, not sure who though, ive seen it talked about on here, maybe someone will jump in with the info, lmc catalogs are really good for this info, i have one for the 73s and up also and there are alot of parts from those years that fit also just check part numbers that match
