I bought a pu off auction and it came with a stripped out mounting screw hole. I don't wanna make bigger holes in my pickguard to accomodate a larger screw and i don't have access to tap and dies that small. Does anyone know where i could get one of them slip on clips with the threaded hole in it? Or maybe changing the back plate is easier than it looks? anyone know the size threading and pitch the mounting screws are offhand. thanks
