Here's a trick we used on the race cars when a non-stock Pitman arm position was needed to accommodate a situation like a narrowed frame, etc. The Saginaw sector gear has four wide spline slots, with corresponding wide splines on the Pitman arm. If an intermediate Pitman position is needed, just take a 3-cornered file and cut each wide spline into two narrow ones. Then a position adjustment can be made by clocking the Pitman arm on the sector shaft one spline at a time instead of every 90 degrees.
