Yesterday I bought an MIM Lonestar Deluxe Strat. It's a pretty impressive guitar, but like a lot of Mexican Fenders, it could do with a few tweaks and mods. One of the first things I want to do is switch the stock machine heads (Standard Cast/Sealed) for Schaller locking tuners.

Does anyone know where I can find a set of these that will fit my Lonestar Deluxe? To my understanding, there are different sized tuners for different guitar headstocks and I'm not sure which will fit mine. I live in the UK so it will be easiest ordering from a company based here. Thanks!
