Just for thought......If your orig crossmember is in good shape, you can swap the 72 disc setup in by changing the ball joints, & use all of the steering linkage from the 72.(centerlink,tirod inners, outers, & sleeves). The only diff in the crossmembers will be brake hose bracket placement. As far as the steer stop issue, I havent run into it personally, but have heard from some guys that have. let us know how it goes, & good luck......crazyL
