i did the autoweld kit and it was a good fit the only problem i had was the anti roll setup they have. i have a 15x10 rim with a 3.5 bs. i also did the offset lower contral arms. i did the 9 inch that is 3.5 inches shorter than a 8.8 on each side. i have a little more than a inch from the rear end to the rim. i did my rear end where i can move the contral arms on the rear end up or down.
