I got my sway bar off of E-bay. Still paid close to 140 for it with shipping. I think it is an Addco unit, but there was no names on it. I am not happy with the mounting on the K-frame. It uses an "L" bracket that mounts the swaybar bracket in an upright position instead of horizontal to the ground. I will be breaking out the welder and solidifying the mount when I put in my subframe connectors. As far as performance goes... I say, don't leave home without it. The car handles extremely well now. I also added in the .920 bars, poly bushings from Energy Suspension and SS springs in the rear with 2" blocks. (I sat on the springs for six weeks trying to decide if I was going to dearch them or not, but didn't want to without knowing how far I needed to go.)
If I had it to do over again, I would be calling the folks at Firmfeel. I have installed there swaybars in several Mopar projects at the shop and all of their stuff is topnotch. These guys do their homework and it really shows.
