I think sticking with the IFS is the way to go. The cons are out weighing the pros on this swap big time. I'm guessing 33" is the max tire with the 4" lift? Also you cannot do a body lift on a unibody correct? Getting the wheels out 2" past the wheel flares how much trimming do you think I would have to do to get 35"? Or is that just a bad idea? I've only hit the under body a few time ( I'm very careful and meticulous about my lines) but I want to take some of the harder lines.
