help identifying part# in diamond drive

[motoxxman]

hello
i have a 2007 M8, with reverse. in my diamond drive i cant seem to find a part number in the OEM breakdowns, they are not showing this little snap ring that closes the planetary assembly , its on the output shaft. in the attached pic its #4. not that larger snap ring they list on the oem breakdown, this is a smaller one. any help appreciated.
thank you

I have been down that road before and they don’t sell just that ring lol crazy. Did you find one yet? I ended up getting one from my cat dealer but it was just from the mechanics extra parts bin that he collects lol.
