I have a 2019 Charvel San Dimas that I did a neck swap on with a used 87 "pointy" neck. The old neck had no tuners and the old Kahler string lock was missing the locking screws. I bought this and it was a direct replacement, fit the old holes, and is doing its job.
Used this on my 1988 Charvel Model 2. The screw holes were about 1 mm wider on the stock unit, but the screws went in just fine anyway. Seems like quality materials here, replacing cheaper, stock parts.
