Either I or the last knucklehead who changed my oil managed to round off the oil plug bolt head too much I don't know what "part" of a bike I would find the oil plug listed under. Can one of you more knowledgeable fellas tell me where it is here:  https://www.revzilla.com/oem/suzuki/2006-suzuki-s40-boulevard

I think it's #17 here. It also lists a gasket (#18) for that bolt, but I never seen one on mine. Opinions? https://www.revzilla.com/oem/suzuki/2006-suzuki-s40-boulevard/crankcase?submo...
