I assume that I'll need some sort of cap for the then-open T-Case output shaft port?
I had a rear spring rattle that baffled me for a bit. it would only appear on coasting and would be intermittent. figured it out by idling the engine and rocking the jeep back and forth. I wasn't hearing it at speed as it was being masked by the exhaust noise but it was there the whole time.
OP
I suppose that could be it ... we were rocking the jeep back and forth to set those bolts into place, maybe we just got a spring off its perch or something?
How did you fix that?
I have heard the sound gain a lot of speed as I sped up, and it sounds rather ...rotational. so I'm not sure.
OP
Mine looks like it does...? I mean I could remove the SY boot and pull that off, is that the intention?
I figured out where the noise was coming from when I could simply squeeze the springs by hand during idle and the noise went away.
I popped the springs out and put these in

mid arm installer didn't put em in as requested. "I never use those there's never an issue". sure..
check to see if yours are there or if they are worn. I'm not saying this is your problem, just something to test for.

OP
It would happen at idle with rocking back and forth, not just sitting there without any motion at all.
your pads are there and look fine though.
OP
I'm getting the feeling that there are two factors at play here - A driveline imbalance that I'll test out shortly, and the ebrake shoes rubbing on something they shouldn't....
OP
so yeah the intention is to remove the slip yoke boot clamp and leave the output shaft in place got it
OP
UPDATE TIME: that weird rotational noise was just some crud inside the brake drum. I took it apart, cleaned it all out, and now its perfectly quiet again. Musta just knocked something look. Regarding the vibrations on the highway, we're in a pretty good spot now! I can get up to 60MPH completely without vibrations, which is a huge victory! The vibrations behind and under me are pretty much gone!
There are still a few vibrations in the steering side of things once you get up to about 65-75 but its actually useable for passing purposes.
Once I get that regular height pitman arm put in and that new trackbar bolt installed I'm thinking we'll be in a really good spot.

Getting the Pinion angle right, though I still have some higher speed vibes in the steering, I'm blaming the funky geometry of the drop pitman for now. I might also need to balance out the front axle a bit due to the lift. its my next hunt.
OP
Closing the loop on this - one of the tires was bad; got a new set of ridge grapplers and the jeep can go 90mph downhill with no vibrations, pretty pleased with that!
Too bad — you should have bought tires that would let you go 90mph uphill. 
I'd like to find some of those too.

Maybe if I get a regear I'll have a hope of going over 60 on the flats, haha
You will indeed. My regear made life much more wonderful, even at 5000 to 13000 feet elevation.

Just buy something tiny
