Internet searches send me to plenty of listings to buy a set of tuners, but what I really need is just the screw that goes through the pinion gear into the tuning post. I’ve got a MIM P bass with tuning machines that a prior owner must’ve went hammer and tongs on, and two screw heads are almost totally gouged out. If I gotta buy new tuners I will, but it seems a waste. Anybody know a source for the screws or at least what size/etc? Thanks!
