Okay, I'll buy what you're saying, but would like to learn from these pics, as there is no explanation...... Is the problem that the draglink is not level and 90 degrees to the pittman arm? The reason this would seem wrong to me is that it wouldn't turn as far to the right, but I was unaware that bumpsteer was a problem on straight axles with straight tie rods unless they are cross steered. Obviously R&P bolted to the chassis would also change toe as the suspension worked.

The "ideal" is to have the drag link parallel to the radus rod, and have the rear pivot points as close to the same vertical plain as well so that when the suspension moves they travel in similar arcs. Differences cause a push me - pull me = bumpsteer. Most cross steers avoid this.Your Uncle Bob, Senior Geezer Curmudgeon
It's much easier to promise someone a "free" ride on the wagon than to urge them to pull it.
Luck occurs when preparation and opportunity converge.
