As Lane said , for safety, best to replace the crush cage . Shift coupler: The red urethane will fail and best to use a German rubber type. Steering wheel to dash alignment : There are two 1/4" locator pins fused to the axle beam and depending the orientation you have the box clamp will put the steering shaft at a slightly different upward angle. To fix your steering wheel to dash alignment you can first remove the tie rods from the pitman arm then remove the steering box and remove two 1/4 pins off from the axle beam with a chisel, this will let you move the steering box a bit to slide to align the steering wheel to the dash and the difference on horizontal placement can be made up by readjusting the tie rods . After you replace the steering box and tie rods and are satisfied with everything you'll need to tack weld the clamp on the outer edge so if needed it can be removed at a later time. You will also need a front end alignment.
