Steve,
Don just said more or less what I was going to say.
The NPD catalog refers to the parts as: Pitman Arm, Outer Tie Rod, LH & RH, Adjuster sleeve (2 req), Inner Tie Rod, LH & RH, Drag Link (center link) and Idler Arm.
Note on the Idler Arm. There was a thread on this recently. I suggest you look it up. Most of the reproduction arms may not look the same as the original, some are better than others. It is the center line measurement between the 2 bearings that is important as well as from the top of the drag link connector bearing/bushing in relation to the bottom frame mounting hole. Hope that make sense!! I bought the NPD part # 3355-1 (USA made) as it has bearings not rubber bushings. Unfortunately this part did require me to slot the top hole for it to fit. (per instruction sheet). Other than that, the geometry was the same. Again, there was a lot of discussion on this subject.... and confusion!, so I hope you're not too confused either.
By the way, this post should be in the Steering section, but who cares!!
EDIT: I looked up the post. Idler Arm Question by Blmeis on 02/03/16 Enter idler arm question in the search box top right and you'll find it there. Good luck.
Geoff.
