Need Help on Bolt Size

Hey guys, I've been searching all over the net today and can't seem to find it anywhere! What size are the bolts that hold the mechanical fan to the water pump? Essentially, what size bolt goes into the pump through the pulley? My truck didn't have any of this installed when i got it, and even though I am swapping to an electric fan, I still need the pulley attached!

Oh yeah, it is a 1957 3100, with the "assumed" original motor, a 235.
