I assume you are referring to the torsion bar being broken. I'm pretty sure those parts are still available through a dealer parts department. Rob the Elder has a pretty good description of how to replace these, somewhere, if you can find it. In order to replace a torsion bar, you need to remove both the rear fascia and the rear bumper cover. It is a PITA job, in my opinion, best left to a dealer to do.
