Ignition switch bracket bolts

[Under Dog]

Apparently the bolts that hold up the ignition switch fell out during my last ride. When I stopped after a 30 mile ride, the ignition switch had wiggled its way down in between the front forks, behind the headlight.

Does anybody know what size bolts these are so? I'd love to hit the hardware store and purchase the right ones on the first trip...

M6x20, if it's too long cut it 5mm or add washers.
