Leaving for a trip this weekend and noticed that my drain cap on my 84 has
started leaking (stupid me forgot the water in the tank last freeze)

I see this is available at the usual places. But I can't seem to get any
orders from any of the vendors in less than 2 weeks, big or small. And no,
I don't live in the boonies, just Asheville, NC.

Does anyone know of a hardware or plumbing store item that would work as a
replacement? This would be the 34mm from what I can tell. I don't think I
can order anything that will make it here on time.

Thanks
