Manual Steering Box Rebuild Questions

Okay so I got my manual boxfully disassembled and all cleaned up inside and out....yes those little ball bearings in the worm gear were not so fun at first either, lol, who comes up with something like that,lol ...and, just have a few questions.

Does anyone sell the seals for the steering shaft and the pitman shaft?

What kind of lube/oil is supposed to go in there? What do you guys run?

When I pulled that thing apart it just looked like someone nearly packed it with wheel bearing grease.

Thanks for your help!
