I wrecked the cover of the waterpump on my NC29 race bike in my last crash (due to the need for case covers to race in Oz, the case cover did the damage!) and had to get a brand new replacement. The part looks very similar and has the same markings and numbers on the cover, albeit in different places, however it doesn't fit. The front 2 bolt holes line up, but the rear one is about 2mm too high and forward.

Does anybody know about the different water pumps on the different models?
