The tie rod ends are different. The difference is right hand and left hand threads used to adjust tie rod. The the size of the tie rod end links do not appear any different in size.

I've considered the idler arm and thought about how that may alter the pitman arm's geomerty if it is the wrong one. Will have to investigate further. I was able to compare the centerlink and initially thought it may have been reversed however, that wasn't the case.
