What size bolts hold on the headlight bucket?

[cmyoch]

I'm seriously considering deleting my turn signals. They are currently mounted to the headlight bucket. Does anyone have a suggestion on what size bolts I will need to hold the bucket on?

Find the metric nut size that spins on the end of the TS stalk (M8, maybe M10), I can't believe I'm explaining this to you. Buy loavers, lol.
