Late Style MS/Servo O ring

[tmsmini]

Any suggestions for a replacement O ring that goes between the MC and the servo on the later style versions?
It comes with a rebuild kit, but the MC does not need a rebuild. I hate to go buy several hoping that one would fit...

I think this is it at moss motors.

That the one, I don't usually look at Moss. I wonder if Moss US has it as well.

For some reason I did not find it at MS.
Thank you!
