Have you chopped the body mount? If your running stock rims you should be fine. However, if your running 16x8's you will probably have to chop.I might have a friend or neighbor help me, as I have no experience with suspension work.
A shop quoted me $325 so I might just go that route.
I just ordered BFG Mud Terrains in 255/85/16- I prefer skinny tires over wide tires.
