I will have the dealer find out. The old bushing number that is stamped on the bushing is 123 326 2081. If you have your old ones you can check to see if its the same number.
Because of your post, which I found in a search, I had them research this and the above part number is the replacement that they got from Mercedes. Everthing about the bushing is the same except it is about 1/8th of an inch taller. Which makes sense. My old one lookes like it would have compressed, after 22 years, about that much.
I'll call the dealer tomorrow and find out.

Dave
