As far as I know the tie rods are the same but, the idler arm is different. The power steering version is suppose to be stiffer that's what they use to center the steering so I've read.
yes, the pitman arms are different. The manual one has the balljoint going in one way, and the power one has it going in a different way (one goes from the top, the other from the bottom--cant remember which one goes which way.) Also the power one is shaped differently, so it will not work with the manual center link
the idler arm goes in on the top on the power unit has balljoint going in one way the none power has like a stud you can remove from the looks of the pitmen they both press in from the bottom the nonpower pitmen has more of a bend in it and it bends up and twist wear it goes to the center link any one have a good Pic of a Manuel unit at the pitmen arm don't want to put it on wrong if it dont go like it looks
