You gotta dig further in parts manual. Once u find that section it will make sense.
No offense taken. It has been a long, long time since I navigated the parts manual. But the actual P/N does not specify which side is "even" and which side is "odd", and I could find neither stamped on the parts, only an "M 24" and an "M 35", and neither is an actual P/N.
