I Want to correct my rear shackle angle. Currently its straight up and down. The rc relocation kit is great, except i do not want to add any more lift. I was looking at it today and it seemed i could extended the shackle box foward and box it in foward to the frame rail and existing box. Looks doable on passenger side, driverside the fuel filler lines are in the way.

Anyone have any other ideas or suggestions to mod my shackle angle without gaining lift?
Thanks!!
