I just got done doing this on my 97 900ss. I used a brand new clutch and brake master cylinders that used on the 916. I got them from yoyodyne. Something to think about is that the choke houseing screws into and is fastened to the clutch master cylinder. I know that the 916 clutch MC has the taped holes to attatch the choke houseing to, I don't know if this is so on other clutch MC.
