I think thr 2wd pitman arm is shorter, but don't know if it would work in your aplication. A shorter arm is not the best way to do it in my opinion. A shorter arm will decrease your steering and not allow you to turn as sharply. For tire clearance issues you could tub the firewall back to the body mount but more than likely you will want to move your steering box and axle foward for that better aproach angle
