I tried searching rockauto.com and this forum but I can't find out what size is the water plug on the end of the cylinder head. It measures as .900" but I don't find that size. Is it 29/32?

Napa doesn't have one, and OReilly's doesn't have one. I'm off to Ace Hardware to see what they have.

Thanks. Paul M.
