Do you have a picture of the pitman arm before filing? I'm trying to figure out what's what for my own edification.
Not the best picture but you get the idea. The pitman arm has 4 raised “flats” that line up with the steering box output shaft 4 “low” flats. That means the pitman can only fit the output shaft in that one predetermined position. If you grind down the raised pitman arm flats, then you can put the pitman in any position you desire. Jerry HOTROD LINCOLN suggested doing this and it saved me the cost and trouble of having the front end aligned because the tie rods never changed.
