Fellows, I just finished recreating an ammeter for my 1916 Maxwell dashboard from the damaged original and another mint Weston ammeter off eBay. After taking my original case and the internals from the Weston I ended up with a perfect recreation of my missing gauge. When I went to hook up the wires I find that the studs appear to be some obsolete 10-40 thread. Anyone have nuts, thumbscrews or some other idea of how to fasten my wiring to this gauge. Local machine shop says I'm looking at hundreds of dollars to make 4 nuts!!
Thanks, Howard Dennis
