Looking for bad S500 self leveling rear shock/strut
 

Hey guys,
As title says, I'm looking for bad rear shock from S500. No matter the condition as long as lower shock mount is there. It can be from 1992-1999 model as long as it's self leveling model.
I have 94 S500 and my lower rear shock mount is loose. There is some noise coming from that shock going over bumps. I'm thinking to at least try to adapt a universal polyurethane bushing in place of my loose OEM mount. OEM lower mount is built into shock. I'm thinking of drilling it out, make smooth surface inside, and press in polyurethane bushing with steel insert. I need one bad shock to experiment with.
If anyone has one to spare, please email with price.
Thanks
