Just got back from picking up the crewcab. I had taken it to a local diff only guy I have dealt with on a few things over the years. I went to him for a re-gear from 4.10 to 3.54 and rebuild as necessary.
He told me both diffs were in good shape, someone relatively competent had been in there at some point. Power loc only needed new clutches, and the front diff didn't even need new bearings.
Re-geared to 3.54's, I had an OEM ring and pinion I had picked up super cheap. I went to a old fellows house to pick up a compressor and when he saw my crewcab we got to talking. Turned out he had recently sold his 92 reg cab dually and had some leftover pieces. I got a mint, but terribly bent one ton tailgate, Dana 70 3.54 ring and pinion, repair manual and some other stuff for $125!
Anyway he only had to replace the front gear set, with a mint OEM set. And he couldn't say enough about how clean and easy my stuff was to work on...such a change to what he usually has to deal with.
All in all a very fine experience! I would highly recommend him to anyone in the area!
If anyone is interested this is his business....
