LooseRocks,
Is that a Part Number A9004 that is stamped on the washer?
Bet if you go to an Authorized MB Sprinter dealer with the photo and your VIN # they can get you the
washers your need for a pretty good price.
Hope this helps,
Roger
That part number crosses to 9068990121 with a list price of $4.70. It does appear to be what you want. Ask your local dealer to show you the picture in EPC Group 68 / sub picture 285 / call out 335 just to be sure.
