what bolt does the tail exhaust pipe clamp need?

[RRrider]

Cleaning my bike today, I noticed the tail pipe was a little loose. Upon inspection, I noticed that what I believe is the tail pipe clamp was still there but there was no longer a screw or bolt, or anything keeping the clamp together, so the two ends are just hanging free. no wonder the tail pipe is a little loose.

So my question is what kind of bolt do I need to put there, and any ideas on where to get one? I'd like to get one this weekend, before I hit the track on Monday (so ordering from a dealer isnt going to work).

TIA for your help.
cheers

and the answer is: an m8x30 bolt (8mm 30mm long) on number three on the diagram on this link.

got it, fixed the problem (muffler is tight now), and I flipped the spacer on top of the shock to add a little ride height and hopefully speed up the turn in a little.

ready for the track day tomorrow!
