Hey Guy's I'm new here and I have invented a way to convert your 9/16 peg head holes to 7/16 so you can use Sperzel tuners. I'm a custom builder from NY and many players have asked me to change there old factory tuners to New Sperzel locking tuners. I say the least it was not a fun task had to alter the peg head with a wood dowel and the redrill the holes again, Now with my hardened bushings they press in and you can then install you new tuners, when you want to change back just push them out and you peg head is back to normal size hole. I listed some info on my website blog.
