Rear Sway Bar

If it's an Addco type (or repackage) it will have flat round endlink bushings like the front of your car.

This is how I installed the on in my Dart: http://www.forabodiesonly.com/mopar/vbpicgallery.php?do=big&p=2062

It's tricky to place the mount on the chassis right where the end link is perfectly perpendicular to the sway bar end link AND the frame mount bushing at ride height with the weight of the car on the suspension. You might need to play with the length of the end link sleeve to get this right.
