I have an 83 Chevy Silverado, 350. Put a new steering gear box on. Not sure how far the pitman arm is supposed to up on the new box, and what tool I am supposed to use to get it that far. I have checked the Haynes manual, and they tell you how to take it off and simlply say, "reinstall is the reverse procedure". Which is true but doesn't help me in this case.
