Gotoh SD-90s or PRS Phase III tuners may fit. On my Bernie, the screw holes lined up perfectly for both. I reamed the holes for the bushings to 10mm to insert the Phase III bushings, but someone on this forum has Phase IIIs installed with the regular PRS SE bushings.
I preferred the look of the Gotohs and reinstalled them last night. The Phase IIIs are much nicer in that everything seems to be built to tighter tolerances using better materials. That being said, I never had tuning issues with either set of tuners.
Considering that I have a SE, and I am not sure what tuners are on the McCarty, you would need to find their dimensions (or measure them yourself), and then compare them to the Gotoh website using the SD-90 measurements. If they are the same, then odds are either the Gotohs or Phase IIIs will work.
