Aor, had problems with the mounts. My axles are 69 3/4 wide per rk's recommendations.
When installed, tires contacted the shocks and the coils weren't even added at the time. To solve this The upper ended being reversed and the lower had to be pushed out so the tires didn't rub the shocks. This prevented the factory calipers from being mounted. Lower mounts had to be ground and rewelded to mount the calipers. I'm waiting for the drive shafts to arrive so we can test articulation and make further adjustments. Depends on the flex results, the rear coils might need to move inside the frame and through the floor.
