Yes they drill the pilot holes for the claw per that drawing; be advised that MANY tremolo claws that come from a lot of sources OTHER than Warmoth have screw hole spacing NARROWER than the default pilot holes that Warmoth drills, which line up with the claws in all the tremolo bridges they sell. If you do not purchase the tremolo from Warmoth they cannot guarantee the holes will line up. You can always drill additional pilot holes yourself, no big deal....
