Clutch lever mirror mount hole

Does anyone happen to know the size and thread pitch of the mirror mount hole on the clutch lever bracket? I suspect its 10mm x 1.25 but can anyone confirm that? I just bought a RAM mount that mounts using the mirror hole and then realized I would need a bolt to hold it in.

I THINK THE SUZE YOU MENTPONED IS THE ONE DOR gl 180 0VALVE COVER BOLT WHICH I THINKWOULD BE TOO SMll.If yiu hVE hRDWrw aroew hNSY GO ns buy AAORTWS SIZES ns rKWW Bxk rhw onwa you don't use.my loxL GW HesqRW Ha GOOS SUPPLY OF METRIC SIZE

They sell RAM balls with that exact thread. I have one on my NT so I know it works!

ps. prior to that, I had a RAM ball with a bracket on the bottom for the 10 mm bolt and I never cared for it because it made the GPS shake too much.

your close. 10mm X 1.5 pitch which is a std course thd in metric , 1.25 is fine thd

It is an M10X1.25 about 20mm long in case anyone is interested
