Like I said, if' you are going in there you might as well do it end to end. No point coming back later. The wiper seals from Milers if yoy buy them separately SHOULD be genuine Toyota. But if you buy the axle re build kit you get a load of stuff that isn't. So better to buy individual bits. The top and bottom bearings are usually KOYO but can at times be other makes but they are all Japanese. I might not put a copy bearing in a gearbox rebuild, but these things are spinning like Billy O. I can't imagine a bearing failing in a swivel frankly. You get your 80 properly dirty as nature intended. You could put genuine red and white packet bearings in there (actually Koyo anyway and they're going to last longer in all that mud are they?) Milner bearings are fine. As so may have said, don't mess with inner axle seals. Mr T all the way. You can clean up and reuse the hub bearings etc and to be fair. coming back to do them another day isn't so bad. Milner 54mm nuts are shite. They are stamped and don't fit a proper socket. As the usual box spanners are also pressed out, they do fit the Milner nuts. No shame in getting the cheap box spanner. It'll work. Milner gaskets are fine too. I've had loads. The rear hub seals are OK as well. They used to be rubbish, but seem to go in fine now. Look for wear in part 43211R / L The bronze bushes can wear where the stub sits in them. You can push them out and swap them 180 degrees if you like. I replaced mine with needle rollers and the shorter bush from the 100 series.
