Can any of you call makers recommend a spring for box calls I can find at a big chain hardware store or the like? I ordered some springs from Dad's Monday, not sure when they'll arrive. I'm working on 4 calls right now and have to swap the one spring and screw I have from an old Lynch call between the builds. It's kind of a pain! Looking for a sufficient spring locally until the stockpile arrives. Any help would be greatly appreciated.
