You’ve got those pretty damn vintage sized Grover tuning machines… but some of the holes are quite a bit wider. No prob, mate, use some natural cotton paper you have left from some prints 😉 Fits pretty well the damn thingy ^^ and much tightly 😉 hottie!
Holes for screws are to be 1 mm as the screw thread is 2 mm wide in diameter. All done!
Vintage means traces of old things, nothing but normal life! Enjoy the extra holes from the past 😉
