I have two exhaust support brackets available for the E500E. This is the metal bracket that supports the exhaust system and attaches both the the exhaust, as well as the rear of the transmission. The purpose of the bracket is to properly support the exhaust as it goes rearward.
These parts are NLA from Mercedes-Benz for some years now. They are specific ONLY to the V-8 W124 cars, and are difficult to find.
These brackets are desirable because they are sometimes accidentally left off the car by mechanics servicing the cars, and many owners don't even know these important brackets are missing off of their cars.
As I said, I have two available. $50 each, postpaid via US Priority Mail Medium Flat Rate Box. That's $35 for the bracket, and $15 for postage.
