I think the shims are about $5 apiece OEM and like $6.50 from Mercedes. Most of the shims can be re-used. I recommend measuring what is in there. Then round out your collection with +1, +2, -1, and -2, where 0 is what you have the most of. Go through the shimming procedure and note what you need using the collection. Then go buy what you're short.

I am not making this up.

There are a lot of posts on this worth reading. There are some real tricks to getting a good measurement with the gauge.
