Small Oil Leak-Rear Seal Help >?

So after a good swamp ride two weeks ago I finally got to fixing my XMR. The belt exploded on me causing me to tow it home. Installed replacement belt last night no prob. Buuuuut found oil leaking out of the rear "main seal"? This is where the rear drive shaft enters the motor. Fairly good leak, need to find this seal. Can seem to identify it online. Seems to be fairly common. Anyone know p/n or link ? Help is appreaciated.
