Number 10 is part number 07119904527. I just got them at an auto parts store since there is nothing special about them. Most are M6X20 class 8.8. Realoem says three of them are a tad longer at M6X25 (Number 9, part number 07119905400)but it does not say which ones on the pan are the longer ones. Mine were missing on the driver side front. One was missing above the support cross member thingy and was really hard to get to. It took a long time to wedge my fingers in there to get the new one in place. For the washers I ended up getting a class 10.9 only because the class 8.8 at the parts store had too big of a circumference to fit.
