To be clear, these aren't the ones in the snout. I think they were in the LIM, and guessed they were just to help align the gasket and supercharger during reassembly. But everything's aligned without them, and torqued to spec. Just wanted to be sure they weren't required for some other reason, but I can't imagine they'd contribute significantly to "holding force" when there are ten bolts torqued down around the housing.
