I have a couple of suggestions. You can search on the net and find a number of European MB parts suppliers. Ones in the UK are most likely to speak English (kind of). In the US, Europa in Santa Fe used to have access to the European parts database. The last time I talked to them, I was told MB took away their access to that material. Euro-Tech Services has access to European parts--at least to truck and Unimog parts. They also might have access to automobile listings.
