Hi. This is the first time I try to install anything on my guitar, and I decided to swap out my old vintage Kluson tuners on my MIJ '57 Strat for some Gotoh Vintage style locking tuners. They came with a set of 6 of those cylinder metal pieces but no nuts/flat washers, and my strat didn't have any nuts/washers when I went to take out the tuners. So, I just decided to install the tuners straight in and screw them in (there was a metal ring in the headstock holes that seemed to be permanently secured though). But when I go to restring the guitar, it is very difficult to actually get it going and when I do I get horrible fret buzz throughout. I'm not exactly sure how to proceed so I would greatly appreciate any help. Thank you.
