dave when you say track bar ? better the a pan hardbar ? your talking a track bar .@ bar crossing the lower two bars working the lower bars mount point s at a cross angle holding the rearend in track with frame off the lower front point of bar and crossing the back rear end mounting point from the other lower bar at lowest point to hold track ? .pan bar many push the rear end abit but if angle is right not much . but with the track bar you see load and unload work thru the rear end at lowest point. l had both with tub out car so the track bar may work better with a car not tub . yes a watts is the best but shuffing that under a car your going to look like a jungle jim set. just my two bits worth i know nothing
