The Mercedes Bearing Number is 008 981 43 25. The rubber support from Mercedes I was not able to find matching number. They seem to want to sell that with the drive shaft. You can get the complete center support replacement at Needswings.com. Not sure what the cost would be for shipping. Also "Partsgeek.com" has the two parts you are looking for search for 2003 SLK drive shaft center bearing. Those are after market parts.
