(6) Tuner machine head conversion bushings black

Conversion bushings designed to mount vintage (for example Kluson) tuners (9mm diameter holes) on a standard headstock with 10mm diameter holes.
Make sure the tuner shaft from your tuners are not wider than 6mm otherwise the bushings will not fit over the tuner shaft.
These conversion bushings will not fit genuine Fender vintage tuners becasue the shaft from Fender is wider at the middle position from the shaft.

Outside Diameter = 10.20mm
