Only thing I can figure is that that arm moves the rod end on the drag link to the top rather than the bottom raising the drag link up the same amount. Meaning the taper in the pitman arm is from the top rather than the bottom.

If you have everything together and a way to slide under the truck with the weigh on the tires so you can slide under the truck and look you might hold something to see a straight line from the rod end at the pitman arm to where you figure it would sit on top and see if that raises it up enough. You can pop the front loose and flip it over an put it in from the top but will be about a half inch high if you just want to do the look and see thing.
