Ring Gear and Pinion should be fine.

I need some advice. I can't bleed the rear brakes. I have a pressure bleeder and can do the front just fine but nothing out the rear. The service manual says to hold in a pin on the proportioning valve. I did that but still nothing. Also fluid dripped out of the pin, not sure if thats right. I also just tried pumping the pedal with the bleeder open. I never saw evidence of any fluid coming out. The level in the master cylinder never dropped. I'm beginning to think the proportioning valve I got from the junkyard is junk. Anybody see what I'm missing?

Are the Bleeders clogged? Pull them and run a small drill bit or allen down in it to push the stuff out. Then Blow out with compressed air.

I doubt they are. They are brand new and came with the new wheel cylinders

Take one of them all the way out. Should get some fluid running out. (Gravity Bleed)
If you get nothing. Pump it a few times. Might have blockage or crimp in the old lines somewhere.

Keep it Simple.

Right rear bleeder has been cracked open since i started trying again this after noon (a couple ours by now). All dry. I removed it and 15 minutes later still dry. Also pumped the pedal a few more times. Nothing. Left the bleeder off and will go look at it again later. I've replaced lines from about the firewall to the axle and blew out the lines that are on the axle with compressed air before installing them. I'm thinking about buying a new proportioning valve and taking the one I pulled back to Brandywine. I cross threaded an inlet on the original. Its the only thing that is different from before other than the MC, which bench bled fine.

Yeah. Something is bad. Crack the lines open at the output of the proportioning valve. Like you said. Bet that's where your problem is. especially since that is different than before. Good luck.

New proportioning valve let me bleed the brakes. Now hopefully bleeding the power steering goes slightly better.

Yeah for the brakes. Power steering is easy.
Fill it with fluid. Cycle a couple times with engine off.
Turn wheel all the way to the left.
Refill. Start engine. Turn right back off. Refill.
Repeat. Until you don't have to refill.
Warning will try to bubble out and overflow as air is pushed out.
Do not just crank it up and let it run. Air in the pump is the worst thing for it.

I like bleeding the steering while it's on Jack stands, or weight off front wheels. (makes it easier to turn without power)
Fill pump and start turning the wheel slowly left and right.
Check pump frequently.
You can get almost all the air out this way, before you start the motor.

Another way to bleed the pump is to put an air ratchet with a hex head to spin the pump. Much slower than the engine turning, but will help get the air out before you put the belt on and start it.

And the last trick I learned one summer in band camp.........
