1 Raye Boals 9 months ago Anybody done this? Just got a G6119FT 1962 Tennessee Rose . Someone "upgraded" to Sperzel Locking Tuners so you have the screw holes from the stock Grover Sta-Tites exposed. I don't like that and prefer the vintage original look. Since it appears the holes had to be enlarged to 10mm or 25/64 and the Grovers are 8.73mm or 11/32 . Can I go back to the stock Grovers without issue and will they cover the small anchor peg on the back of the Sperzels?
