2003 YZ450 and Hayabusa Coil

Hello all, my friend has a 2003 YZ450 that we suspect the ignition coil going out. I'm aware of the Hayabusa coil mod on the early model 4 strokes and my question is does the Hayabusa coils directly replace/readily drop into the 2003 450? I'm only going with the Suzuki coil because they are more plentiful and cheaper over the internet than the 450 coils. Maybe I'll do the coil swap to the 400 with one of the left over Busa coils if we go that route :thumbsup:
