I've recently discovered that the rear sway bar in my GTP is a 22mm Speedbuilt. The suspension was in terrible shape when I bought it, so I replaced the struts & springs. Ride improved but annoying clunk in the rear remained. I thought I had play in the sway bar endlinks so I installed Moog endlinks, but the play & clunking was still there. I noticed the right side bushing was shot and allowing my sway bar to bounce up and down quite freely, which is likely the cause of my clunking. At the time I didn't know any better so I purchased some stock bushings, but found out they rear sway had been replaced with this beefier swaybar. I contacted the person I bought it from who told me it was a Speedbuilt 22mm rear bar.

Currently, the failed bushing is installed into the stock bracket, but I have not been able to locate a replacement bushing that would fit the bracket. So I'm wondering if there is a 22mm bushing that will fit a stock bracket, or if I should go ahead an get some universal bushings and trim them up to fit the bracket. Or if anyone has a better idea I'm all ears. I'm assuming I could use whatever bushing and bracket is used on the Addco (which seems to the only 22mm bar still available for this car), so if someone has a part number for a bushing that fits that it would be greatly appreciated!!

Thank you all
