Bolt size?

[msggunny]

Anyone know off the top of their head, or going into what ever knowledge base they have, what the bolt size and thread pitch is for the bolts on a 2.25L water pump, the long ones?

I cant find any that match at my local store.

I have one that is striped out and want to get a tap and die to fix it, i also need a longer bolt so i can fit a bracket for a GM alternator conversion.

Thanks!

And for those who don't know its just US fine thread. The frist time I saw UNF I didn't know it was just national fine. most mech know it as NF and machinists know it as UNF. when I was living in England I went nuts buying tap and die sets thay were cheep as chips there I got whitworth and BSF lots of them then I saw a UNF set it was beautiful set made in Sheffield England wooden case and I got it for 14.00us. later I found out what it was but still glad I got it.
