I need to replace the tuners on my 1992 Gibson Les Paul Studio. Upon trying to find some it appears there are two sizes, 10mm and 8.5mm. I've never replaced tuners on any guitar but I think this should be pretty straight forward if I have the correct size bushing. I have to replace them because when I was changing the strings one them actually came apart and another one is so sloppy I think it will probably fall apart too. I was able to reassemble the tuner and reinstall it and once I put tension the strings they seem to tighten back up. But I would also like to add locking tuners just for ease of changing strings with locking tuners. I'm not sure what the sizes 10mm and 8.5mm refers to exactly but I'm thinking that is the size of the whole that is drill into the headstock for the peg to go through. But I was hoping one of you smarter than me folks could tell me for sure which tuning keys would be correct. I am looking at these Kluson tuners.. https://www.stewmac.com/parts-and-h...evolution-series-g-mount-tuning-machines.html Would those be the correct ones for a '92 Studio?
