Rear end seal part numbers

I'm going to service my rear end in a few days. The guy at Auto Zone was.... We'll say inexperienced with looking up parts. Has anyone done this recently and possibly have some part numbers. I'm changing fluid and that gasket is no issue. It's the rear hub seals. I notice there is a seal on the inside and then an o-ring on the axle flange. Would that come as a kit? Also, does the diff fluid never enter the hub?

Anyone know what the o-ring seal on the axle flange is called?

Here's the seal for your truck with o ring. Yes, the differential fluid does lube the bearings and seal too.

Thanks man. That is the hub seal, but there is also a separate O-ring that goes on the flange on the end of the axle shaft that seals it on the outside. The manual says to "carefully remove" it. But, I'd rather have one on hand if I can find one.
