Steve's Wholesale Tools is usually a good source. At least, they used to be; they were like Harbor Freight, except they carried "real" tools, but I haven't been up there in quite some time.Awesome, I'd never even heard of such a thing. Know of any local sources? it's a 14x1mm left hand thread, don't know if that matters or not.
Edit: Here's a link to their "Locations" page: https://www.steveswholesaletools.com/pages/locations.html
