I don't know a Eaton from a sack of hammers, but If you pull this thing apart, the seal will have a number on it. If no number, you dimension it by ID, OD, Lip Style and Thickness. As far as gaskets go, I think the only place one is needed is the cover, and I didn't think you were going to mess with that. Axles would get a bead of silicone to seal.
Judging from the pictures, you are going to need some rust blaster on the lug nuts before they move. If you try and replace the drum and wheel as a single unit, be very careful as you can rip up a brand new seal quicker than you can say Chicago Rawhide.
