Hi - I have 4 Gotoh tuners taken off a Hartke XK-4 bass.
These are used but show really minimal wear and work fine. What you see is what I have...I don't believe I still have the small screws but I can look again.
The threaded part of the post measures 7/16"
The threaded bushing measures 8/16" (half inch)
So the peghole on your headstock should measure 9/16" for these to be a good fit.
I'd like $45 shipped CONUS but I'm open to offers.....
Thanks!
John
