Sweet, I think the rears are 6" to the inside and the front 4.5" to the inside but I wouldn't recommend the 9.5" wide fronts like I have rick. Go with a 9" or 8.5 if possible to avoid control arm interference issues. The best bet for you is to take it to a wheel shop and have them measure your wheel size for the max offset since yours is 4wd and mine is 2wd.
