The winged tuners on my '88 Custom 24 are falling apart, and I'm considering switched them out with the new Phase III tuners. Will this present me with any issues? Are the holes in the headstock the same for both? Are the pre-drilled screw holes that secure the tuners aligned on both?

I love my vintage PRS and don't want to do anything to mess with it. Would this be a safe switch to make?
