Just an FYI for anyone who has a car with the second generation Chrysler LH chassis (Dodge Intrepid, Chrysler 300M, Concorde, 300M). You can buy the stiffer rear sway bar from the police Intrepid or the 300M special for only ~$20 from the dealership. Kinda crazy since the "regular" bar cost several times as much. Along with a couple of cheap bushings and an easy install and you're in business. More info here:
