Okay, so I've done a bit of research (since posting a similar thread recently), and am wondering if I can fit GFS vintage tuners on my Squier without drilling. I have been told that I will need to drill, but my tuning holes are 10mm which I thought was standard. Am I wrong in thinking that 10mm is the modern standard? The conversion bushings available at GFS are listed for 3/8" which is just a hair smaller than 10mm. I'm getting quite confused, and would just like to figure this out; any help would be MUCH appreciated. here are the tuning machines: Wilkinson Fender-Style Nickel Tuners- Six for Strats and Teles. here are the conversion bushings: Nickel Vintage Tuner Conversion Bushings -gcc PS - would I save myself a headache by simply dropping these 10mm locking tuners in? Gotoh Style Chrome Locking Tuners- Six In Line- True Mechanical Lock also, does anyone have experience with either of these tuners?
