For anybody like me, you might be curious how this fits and what it fits. I can't speak for everything else but this fits directly onto a current gen squier bullet strat hard tail. Screw holes line up perfectly. A few other bridges I looked at had the holes in slightly different spots, and in the reviews people explained that they had to drill new holes to make them fit, which isn't that big of a deal by itself, but I prefer to be able to switch back with no hidden unused screw holes. I bought this one purely based on the 78 mm measurement and the fact that the screw holes appeared to be in the correct spots, and they were! The screws are slightly shorter but no big deal, they work!
