The Eagle community and Eagle's Den (not sure why it isn't called Eagle's Eyrie) forum have done a really good job getting the parts books and service manuals scanned and online.
Section 9 of the parts book covers axles:

Here's the Disco axle parts diagram:
I made a .xls of the parts by group and part number, but here's a giant wall of text:

Hmm... tabs don't work the same way in a code window on this forum...
Next step is to knock the diff apart to get industry numbers and vital dimensions off the bearings and seals where applicable, as well as seeing what items relating to the disconnect mechanism are rusty or in need of replacement.
The Dana 30 "master rebuild kits" that I've seen didn't cover the bearings and such for the disconnect unit. The Dana 30 IFS is an oddball application compared to most Dana 30 uses, BUT the guts of the disconnect mechanism should be exactly the same, with the possible exception of the length of the intermediate shaft being different between the solid axle and IFS units.
So I can *probably* just order a pumpkin rebuild kit, disco rebuild kit and probably (maybe?) a R&P set and be done... but need to have the parts out to begin with to verify kit contents.
Also, when I filter the tables above for the 3.54 Disco configuration, I get this data:

"Case" in AMC (and Dana/Spicer?)-speak means the part the rest of us call the carrier.
