I decided to spring for some Kluson locking tuners for my 72 tele reissue. However I can’t figure out how to get the old ones off. There’s two screws on the back and I assumed that would do the trick. But, the shaft is bigger than the bushing so I can’t remove the tuner one I’ve got it unscrewed. I’d prefer not to destroy the old tuners when taking them off, so anyone have an idea here?
