Honda 420 rear output drive shaft seal

Well here’s the story boys.. Blew the ring gear out of my rear diff in Catahoula teal hunting, and noticed there was oil coming out the rear of the motor where the drive shaft comes out... I’ve done some digging and found out that it’s a seal that is broke. I have tried to find them online with no luck, if anyone could point me in the right direction I’d really appreciate it! And also, is it just a seal or is there a bearing that needs replacing there too? I’m getting ready to bolt on a new rear diff, but I’m not going any further until this leak is fixed! Any and all help is appreciated! Thanks in advance fellas

    Ok with out knowing the year I went on partzilla and used a 2010 year model. So if you look at the rear crankcase cover there's an o-ring. That looks to be about it.

    My bad! Its a 2012 honda rancher 420te es, i was thinking the seal would be a part somewhere along the rearend on partzilla not the crankcase.

    It's gonna be the rear crankcase where your shaft slides in to connect to the trans. That's where the oil was leaking correct?

    Yep same o-ring. Get you a case gasket and clean the what where the o-ring rides on it with some red scotch bright. Probably when the diff went the prop shaft dropped and wore it.
