I think I've got it right, First I had to define full bump
for me. I kept cycling the axle up and articulating until it would hit something, then I would move or modify that something. First was the rear passenger footwell, which I massaged with a hammer (a few pages back) Then it was the body and tire. Since I'm going 37's a lot of metal had to be trimmed off. Right up to the wheel well. I defined this as the hard limit to up-travel for me. Tires and suspension would not be allowed into the passenger compartment. So I took the tire all the way to the bottom of the wheel well at full flex... And I located the shock tower from this position. As luck would have it, the shock towers from Poly performance are the exact height needed for this. coincidence?
The front of the wheel arch I intentionally squared off slightly instead of a circle or oval. I thought it was more in line with the original shape of the flares for a TJ and looked nice.
Those big ole 37's tuck in there nicely.
I've already mocked up the 4 link.
All I had to do was use two grinders, 6 cutting wheels, 2 flappy discs and about 4 hours and the old brackets came right off!
I fabricated the upper truss mounts, the ones from Artec just weren't working. I wanted a little less separation on the axle side to keep the anti-squat and roll center a little lower. Vertical separation at the axle is 8" and separation at the frame is 6.5".
