doesnt really matter, as long as its wider then stock, ride height, isnt going to be affected as I'm sure I'll tackle the front first which should give me a base to work with, suspension geometry should (hopefully) stay the same, mounting is going to be easy, as I'm already talking to my cage builder and we both agreed that doing a full length 2x3" frame and raising the floor boards is gonna make a world of difference, but we'll see when it comes time as I'm still looking at a couple different rear ends.
I'm not going in totally blind and if i get stuck somewhere i have some BIG resources to help me along the way.
