Anybody know what size the brake stay hole on the drum is offhand?

I'm putting together a threaded rod/heim joint setup for my brakestay, was wondering is anyone knew off hand what size the hole is for the brake stay mount on the drum? I realize I'll need to ream it out a bit to use the standard heims:

I want to pick parts up during lunch but I forgot to measure before hand....not sure what size heims I'll need....

Drill bits as gauges.
15/32 is sloppy. 31/64's too big. 1/2" is what you're looking for?

google says 15/32 = 11.90625 millimeters
31/64 = 12.303125 millimeters

i think its pretty safe to say its a 12mil....
