Bought a new F 250 deluxe as a take with guitar.beautiful looks, excellent sound.Changing to unbleached bone ,saddle ,nut, and bridge pins. My question is, i cant seem to find upgrade open back tuners,to replace what came with guitar.Everything im seeing is too short posts . grover 97n ,V 97 .want gold, not looking to spend 180.00 plus on waverlys.
