Is the MB star and part number really ground off. My experiance with aftermarket OEM parts is that the aftermarket line is different than the parts they sell to the manufacturer. The stuff they sell to the manufacturer has to meet the manufactures specification. The stuff they sell to you has to meet a price point. Alot of these parts are built on two different assembly lines.

A good example is engine mounts. I will not buy an engine mount for any car from any place but the dealer no matter who makes it.
