Good tips as usual on Vanpelt's site.

The ball (drag link pivot point) is slightly AHEAD of the axle center line when the steering box is 'centered'. Those aftermarket steering arms (which actually form a hoop) like the one in your 'BRAKE' picture, CENTERS the drag link pivot point directly over the axle when the steering box is 'centered'. Picture #4 shows another angle. The simple GEOMETRY has been slightly altered with that aftermarket arm such that as when the drag link pulls the arm AFT during a RIGHT turn, and because it is already THEORETICALLY farther rearward than it should be BEFORE it begins to move, SOME travel will be limited. For the same reasons, when attempting a LEFT turn, the steering box will impart a little extra travel forward, likely making your 'lefties' a little tighter than your 'righties'. Other than that, about a bazillion of those aftermarket arms have been used the past 80+ years or so, and most folks likely won't even notice the difference. Hope some of this helps you!

Another couple of my pictures regarding geometry.

And I thought both left and right turns were somewhat restricted by tire contact with the split wishbone

Ah.....That Sir, introduces a whole new set of circumstances! It's good when some folks think outside the box. DD

There's another front end geometry principal that is often ignored or forgotten. An imaginary lines drawn through the pivot points for the kingpins and the drag link ends should create a triangle that points at the exact center of the differential. The wheel base establishes the angle of the steering arms on the spindles. Later spindles from vehicles with longer wb should be adjusted to correct the angle when used on an earlier vehicle with shorter wb.

^^ That's right, Tom, it's got a name. Ackermann steering geometry.
