hi mike because I'm using full size axles from a quadratrak Cherokee and the rear diff is to one side..... Ive got a 7 chassis that I'm stretching to about 104 wheelbase with a cj tub,full cage etc with a amc 360/4.0ltr th400/quadratrak on 37" maxxis creepy crawlers. I'm sick of smashing up my cj5 that i rebuilt about 4 year ago...cost me to much to destroy...
