You don't have to drill anything. Get M12x1.5mm helicoils and put them on, much easier and less messier. You can either use R33 GT-R bolts or get your own high tensile ones (M12x1.5mm, 45mm long I believe, I put 40 and 50mm on mine, both fine).
As mentioned, the rotors are all the same for R32-R34 Brembo except rear R34 V-Spec (not relevant to you).
