So I wrecked my bike and in the process of repairing it. One of the things I have a question about is the Upper Cowl Stay Bracket. The one that the Speedometer bolts on to.

I cracked the left side of it off and the speedometer is hanging out. I believe I may have lost a bolt or that went with it. What exactly is the size of bolt that connects the speedometer to it? I tried looking on the Cheapcycleparts OEM map of the bike, but I would feel more comfortable having a direct answer from someone who knows to back my theory up. Thanks!
