I am trying to find some spacers for my Fender MIM 50's P neck to get a few extra turns. I took my nut into a big local hardware store and they didn't have anything that was the right size.. the 3/16" spacers has the right sized hole for my nut but were too wide overall.. I would have bought them but I don't have a grinder to grind them down to size. Does anyone have an idea of what sized spacer to use? That way I can hopefully ring around some joints to find that specific size. This is for the heel adjust neck btw.
