I respectfully disagree with you 78Buckshot. I think the torque tube (enclosed driveshaft) that is solid from the rear end to the trans, needs the extra support of the crossmember and rear trans mount because of the up down motion of the rear end. Apparently the engineers at Chev. GMC thinks the same way.
