Hydraulic fluid doesn't care which direction it flows, and the Pitman arm can be clocked to any spline position by taking a 3-cornered file to the four "wide" splines on the inside diameter of the big end. That will allow the Pitman to assume the right position no matter what the angle of the worm gear shaft is. We used to use that sneaky little trick when repositioning the steering gear on some of the dirt track race cars we built.
