OK Dave, free advice time though I would gladly send you check. My '73 Mach 1 has a "new", by receipts, steering box (PS BTW) yet an azzload of slop. The rest of the steering components appear to be tight and it is clear eyeballing things that the wheel movement starts before the output of the box begins. I found a fair bit of slop in the worm gear lash adjustment but not all. As I have been lead to believe, one should back out said lash and tighten the input shaft bushing nut first, then the lash. Thoughts? PM if needed.
