If the backlash and tooth patterns were way off, there is probably odd wear patterns that may have resulted. Sometimes no amount of adjusting will yield good contact patterns on worn gears.
My trick is to swap the third members front to back. Most likely 90% of the load on the gears during the trucks history was during driving forward. By swapping third members end for end driving forward is now putting all of the pressure and wear on the "backside" of the teeth from where it has been for the past 70 or so years. The "backsides" should have less wear and should be easier to get that desired tooth pattern.
After doing so, just don't move any extremely heavy loads in reverse. Which, one should not do anyway as the axle shafts take a twist over time and can be easily snapped with sudden heavy loads applied in reverse.
