Emergency exhaust question. minor issue.

[kyraeus]

Hey, I need to get a quick answer on something, hoping someone's on between now and about noon today (5/21). I need to grab a new bolt for my exhaust system (the one near the rear of the bike, parts manual lists it as 01580-10303 (diagram fig 13, pg 14, part #6). Does anyone know the dimensions on this bolt and possibly any accompanying nut/washer?

I've got some noise with the muffler hanging loose, and I figure they likely won't inspect it like that. Was hoping I could get numbers to make a quick stop at home depot to get one to replace it with on the way in today.
