Move upper arm mount rearward to allow caster adjustment

Wow. Yall think in too much work thoughts. IF I was going to do anything, I would relocate the front A arm brackets on each side out a little and the rear brackets on each side in a little. The same amounts, of course. You could gain a ton if you did that. Much simpler than moving k frames and such. You'd be doing what the offset bushings do, only changing the chassis instead of the bushings.

The issue i see is that the bushes will be under more strain. the bolts are parallel but when you adjust the offset bolts it has to put an angle in the bush for the top arm to twist to move the ball joint position. Fine if your bushes are soft rubber but not fine when the bushes are a harder material. I have QA1 top arms with quite hard bushes.

plus i moved the K frame for additional reasons as well so for me it makes more sense to do what i did.
