In Matt's defense, the POL kit came with one little triangular piece with one hole in it. To be welded to the top of frame. His angle bracket is just fine. It will only carry about 1/4 of any load. It is as strong as the welded triangle. I too mentioned the backing plate, but if the kit does not mention it, I would assume they know it won't be needed. As far as the Pitman arm, assuming that the mounting instructions were near followed, as to where/how the box mounts, would it not be at the angle the kit wanted? You have to have the box input shaft aiming upwards toward the column. If the drag link/pitman do not cause the tie rod end to exceed max angle, the pitman shaft will not see any extra load. That's what a ball joint type end is for.
"Suspension Ball Joints (SBJ) are commonly applied between control arms and wheel carriers or knuckles of the suspension that allow relative articulation and rotation between the mating components. Depending on its application, the ball joint can transmit longitudinal and lateral forces with only a small proportion of axial/vertical forces."
As far as the angle bracket rotation, I only mentioned it "could" be a problem. I don't think it will be but if it does turn, then use a longer angle and use the other bolt sticking up as the second bolt. The angle bracket will not twist then.
