Rear quarter lip mods?

this is why they make off set shackles, inboard leaf spring kits and wheel tubs - as stated above grind a small amount off if you HAVE to, but bending the metal is iffy at best and once you've done either, there is no going back.. relocating the springs can be undone. How much room do you have inside (toward the leaf springs)? Maybe it's time for a different wheel/tire package...
