Clutch fork length

It depends on two things. The first is if you have the room for that extra 2" going towards the frame and such. The second is if you do, if the fulcrum point is in the same place. If it is, it would be possible for the clutch fork to move the throw out bearing "too much" when depressing the clutch and put it in a bind. It the fulcrum point is "out" a little further, it could work ok. The best thing to do is get the correct length.
