Allmost all the aftermarket rear sway bars, not just Addco are pretty much the same, the mounting systems supplied suck!,....I've done a few, best advice is to mock up the rear bar on the frame rails, make new plates to relocate the threaded rod ends, or remove the axle shock plates and weld permanate plate extentions (beefed up), custom length bushing end rods/struts are avaliable at most AZ, or CarQuest, Advance, Napa stores, they can be purchased individualy



The Hellwig bar that bolts on to the rear axle, and has the rod ends mounted on the frame is a much better choice, incase you decide to change out the Addco bar
