I'm thinking about buying Sperzel Locking 6-In-Line tuners for my PRS SE Santana (see pic). Tuning stability is an issue, even though I have had the bridge blocked off and the nut replaced. I Was just wondering if these tuners will fit in my PRS. Anyone able to clarify? Or recommend anything better?

Oh yeah, picture.
