If you're trying to replace it you'll NEED the OEM part.
That nut is counter bored.

Just need to replace the sprocket and am wondering what size socket to buy for the nut.  From my caliper measurement it seems like it is 31 or 32mm?

I confess that I just used 1 1/4 inch socket on mine. Kinda difficult coaxing it on by gently tapping back and forth. Worked fine though, after making sure I had full engagement. Used a Harbor Freight electric impact driver.

32mm = 1.2598", so you need a 32mm socket or 1 1/4" if it will cooperate.
