Making some small progress. I took Xeen's advice and went in search of all of the parts myself. Ended coming across a pretty complete kit for the rear end on ebay with an Eaton posi unit, Richmond Excel 3:73 gears, and all the seals and bearings. Then I ordered a set of Moser axles and was good to go. Dallas Differential was able to clean it and put it together for $350 in labor.
Next I ordered a disc brake kit from POL which just arrived today. Can't wait to start playing in the garage again!
