Ok, I got my bumper mounted a few days ago. And I noticed that the basket would be more user friendly if you could take it on and off without having to have a wrench or socket. Say you got to where you are going and wanted or needed the ladder free. So I went to looking for a threaded knob and I have hit a brick wall trying to find one in the particular thread pitch that is used. I know there are other ways to skin this cat, but I wanted to see if anyone knew of a source for a 7/16-14 knob like this one. I have found every size but that one.
