I finally decided to tackle the motor mounts on my '86 300E. High miles and vibrations in the wheel/body are the reason. I purchased the mounts at the dealer. After removing the left mount, I noticed the part numbers are different. The part number on the original mounts is 201-240-43-17. The new ones are 124-240-19-17. I realized this 2 hours into the job. Oh, man. This repair seems easy enough on paper and may be if everything falls into place right, but that never seems to happen. Did they sell me the wrong ones? Thanks in advance.
