I recently bought a used set of Fender "F" tuners to use on a project bass I'm modding. They are the ones that have the two small posts that stick in to the back of the headstock and don't use screws. So I need to drill two small holes for each tuner in the back of the headstock. Does anyone know if there is a template available for this? I checked the Fender site but didn't see any thing. I just want to be as accurate as possible on the position of the holes.
