Also wondering if there is a rear sway bar that will work since the car has been mini tubed.
The frame mounts on the sway bars I've seen look like it would interfere with the springs and the sway bar would make contact with the wheel.
I bought the Helwig kit and had the side arms bent at my local spring shop, so it would fit between the narrow spring locations. Tried to get them to manufacture it, but you know how that goes....
