SBC pulley bolt sizes dumb question but I can't find them anywhere, does anyone know what size the water pump and balancer pulley bolts are? I've gone and just bought everything I thought would fit at HD and come close, but nothing seems to fit quite right 
I thought maybe the parts stores would carry them in some sort of dress up kit but no dice. While I'm on the subject, I can't find a fitting to fit a stock mechanical fuel pump outlet, if anyone happens to know what size/type it is, looks like an AN fitting but nothing I've tried fits there either.

I looked last night, its 5/16. Did you try fine thread of corse? you could try cleaning the threads with a tap, but I wouldn't redrill the holes or you may have problems with the pulley.
