I've been up all night so not thinking too clearly, but I know your solution for the Pittman arm issue.

The basic 3 problems are:

1-You already own a particular high steer that requires 80 tie rod ends
2-The best Pittman arm is the 80 stock Pittman that has the wrong taper
3-I think the 80 TRE has too small of a taper to make re-cutting the Pittman taper practical


So the solution is totally custom and trick--

Use a GM 1 ton at the Pittman end. That end is totally sealed, has a zerk and is seriously heavy duty. It could be right or left thread. For sure, the 80 Pittman can be cut to this taper.

Use an 80 TRE at the knuckle end, with the opposite thread, either right or left.

The only difference is the thread cut in the drag link tube. Then go ahead and use the 80 pittman and have it bored for the GM 1-ton taper.

That nets you the best of all 3 worlds, and makes maximum use of what you already have.

I believe that only Luke Porter at 4x4 Labs could do this for you, but check around. I'll even take the Pittman up to Luke and have him cut it if you go that route.

For the lengths of the linkage, you'd have to ask Luke or Marlin.
