Time for a brake.

[Desert dog]

It's time for a brake, job that is. After quite a delay in getting started it's time to bring the ol' dog back to life. We'll be starting with making it stop before making it go. And to that end we're starting with the rear axle. I believe it's an Eaton HO32 non posi unit. I'd like to service it and gather up the parts prior to starting so, if I may, my questions are as follows:
Are axle bearings available? And if so are offset bearings available?
What size seal are needed for the axles?
Are rear cover gaskets available?
Gear oil weight?
Is there a brake rebuild kit available for this axle?

Thanks in advance for your time.
