I think the pitman is master splined to 4 positions meaning 90 degrees off.
If all else fails, filling the master spline away at the steering wheel takes about 5 minutes.
I was working on a similar issue last night. Both the manual box and the PS box are splined on 4 sides. so it is easy to put the pitman arm on 90% off. if that is the case, then the ONLY way to fix it and still be able to steer equally left and right is to pull the pitman arm, center up the steering and the steering box shaft, and put the pitman arm back on. Use a pitman arm puller, don't beat on it.
