W208 door edge trim

[stereophoney]

Yesterday I was driving along and noticed something flapping around in my wing mirror. It flew off before I could stop. Turned out it was the trim that's on the door edge to protect it from knocks when opening. Does anyone know the part number and where it can be bought?

Do you mean the side moulding? (Plastic strip that goes the length of the door about 6 inches from the bottom)
