I am curious about the difference between the ABY and AAN exhaust cam sprocket with their integral cam position shutter wheel (034109105) and the RS2 one ( 034109105B).
We have this photo (from Tom S.) but what about the back side (of the sprocket, not Tom S.
) showing the position of the opening in the shutter wheel:
