I have a gm 10 bolt front 3/4 ton 8 lug axle. the disc on it has like a metal hub, these axles where off a fulltime 4x4, i am wanting to get new disc but do i have to get the ones with the metal hub around it, i am going to get brand new lock outs for it also. oh yea the the new disc with the hub cost like 100 bucks a piece, without is like 100 a pair!! thats why i am asking.
