Some of the things I've learned about the Dodge LH drop Dana 60 have been interesting.
First, theres a lot of these out there being swapped out by Dodge owners to get rid of the unit bearings or to add locking hubs (not to mention junkyards, these are pretty common, built from 94 til 2002) but from 94 to 99 the easy way to do both is to swap from the knuckles out for Dana 50TTB parts.

This makes these axles an alternative swap candidate.

Of course, I have either a 2000 or 2001 version according to the BOM number. So I can't do that. Difference is in the way the ball joints are mounted, the later ones have the nut on the bottom. What I can do is to source a left passenger (long) axle from a 2002 version after Dodge did away with the CAD system.
I found one on craplist for $125, but can't get it for probably a week.
So, to keep this almost in my budget I'm going to plan for a ring & pinion, a lunchbox locker for the factory 32 spline open diff and to add the CAD delete axle shaft. This assumes the unit bearings aren't too bad, in which case its pretty cheap, really.
Later, I'm going junkyard scrounging for the four control arms and track bar to mock it all up in the truck. The stock control arms aren't very long but I need to reference it all to see how it might be modified into my junk. At the very least, it'll get longer arms. Thinking I should use coilovers too.
But don't hold me to any of this. I'm still deep in the learning curve.
