As JoeH says “ arms are where they are for a reason“.
When I did my adjustable drag link it was only to center up the steering wheel at middle of lock to lock, but I considered this question quite,a,bit.
My conclusion is that the location (on my 46) at 4:30-5 o’clock position was chosen to compensate for body roll when cornering, not necessarily bump steer.
Since the steering box is attached to the chassis and the attachment to the left wheel is at a somewhat fixed height…..body roll raises and lowers the steering box/pitman arm.
As you turn right the left side chassis/ springs compress/lower, so the pitman pulling back raising its lower pivot point, when you turn left the left side of chassis rolls up, and the pitman rotating forward lowers. It all keeps the drag link a little closer to level at any given time.
The opinion presented is just that….
