Tonight I was getting ready to install my spohn anti roll bar and noticed that the rear tires weren't in the same place in the rear tubs, so I measured the wheel base on each side and came up with 109" on the right and 108" on the left. How can I fix this? My rear suspension consists of an A body 12 bolt with Lakewood lower lift bars and TRZ double adjustable uppers. My uppers are both set at 10" right now, should they be equal length? Thanks
