Chassis Engineering website states a rear bar is better than a front to prevent body roll, and I've got a lot of that. Have a Maverick 8" housing with wider tires, the CE bar that mounts on the frame behind the axle looks to be within a 1/2" of the sidewalls. I've looked at early Mustang bars but I'm guessing the frame narrows over the axle unlike the 40 which are straight. Narrowed control arms on the front MII aren't the easiest to adapt but I may have no choice. What rear sway bar works for you?
