For the very first time today, I tried to clean the under carriage of my 2003 E320 4Matic Wagon (It is still a W210). I got the wagon only a couple months ago and now the snow is finally melted (still have some on the ground), I thought I would give it a through cleaning.

To my surprise, I did not find any of the four jack pads (I think it is called a plug). I only found the holes (facing down) near the factory jack holes on the side skirt. When I was reading the MBCA Star last night, there was an ad selling jack pads (as a tool which is an aluminum circular plate with a rectangular adaptor) to lift some C and SL class cars. The ad says that many late model MBs do not have the jack pads and need the special tool in order to use a floor jack to lift the car.

I have a 3 ton floor jack that has a very large lift area so it won't fit there without damaging the plastic side skirt and floor pan. I would have to (at least) find some hocky puck type of metal or rubber pieces.

So my two questions for the experts are:

1) Does my wagon have the rubber jack pads (plug) like the ones in my 1997 E320? Maybe the previous owner removed them for better looks? I can see how these 4 black pads disrupts the otherwise smooth brilliant silver side skirts.
2) If yes, what is the part number?

I searched many online catalogs but cannot find it.

Thanks in advance,
