Crankshaft Pulley Bolt Size

[MichiganSpecialRPS]

Can anyone tell me what size the bolt for the crankshaft pulley is on a 2.3L (1988 Ranger specifically)? I know it's probably metric and is a fine thread. My bolt was missing from when I bought the truck...

That was pretty annoying. I forgot the size I just read something about it last week I think.
