I decided to convince myself that it is all good.

Wonder what happened here, though.

Yikes, that looks like it got rusty and somebody patched a poor cover over it.....I would look into it more and get that fixed.

I agree with Keith; I too would check that out.

I shot a video of the inside of the rear axle. I hope linking to it vill work. I sure hope it's ok to leave that yellow marking goo in there.

Can anyone make any sense of the "pattern"?

At roughly 0:52 in the video, I show the play (backlash) in the gear. Is that much play ok?

The yoke has some surface rust and I hear this version is a little brittle. Should I invest in something more sturdy?

Brushed off one of the brake calipers. I think it came out pretty nice. They seem to have been black originally. I'm thinking maybe I should paint them Mopar blue now that I've got a can of paint. But maybe that engine paint isn't heat resistant enough.

That yellow looks like the marking compound used when setting up a rear end ring and pinion.
Before spending money, I'd wire brush the yoke and take a look at it. They don't tend to go bad. Caliper color - ay color you want; it's your car! I will be using the same calipers on a 65 Barracuda my oldest son is getting for his inheritance - painted them cast iron grey.
