Does anyone know the approximate serial number series for the common replacement of Young Chang parts. Brackets, knuckles, jack buttons. I have a #51xxx G-150 that definately needs brackets (116mm spread), and buttons. But I'm thinking it's a bit too old for the common hard Chang knuckles. They don't seem hard, and might be ok, but I don't want to skip something that may need to be done. Thanks for the input.
