Water pump pulley bolt size

Does anyone know the size and thread pitch of the water pump pulley bolts? I got new 5/16x24, no luck. I'd figure it was metric but I have no idea.
Thanks

It'll be metric, probably 8mm 1.25

I found one of the old ones. I'm going to go match it when the store opens. Will post the size.

M8x1.25 is confirmed to be the correct size.
