Sorry for the slow reply.

None are easier to find parts for, the units in the list haven't been manufactured for 50 years or more. The most common boxes seem to be the various versions of the Spicer 5831, followed by the 41 through 48 Watsons. As long as the gears and case are in decent shape you are in OK shape. The bearings are available and you make your own gaskets. The expensive part can be the yokes to work with your drive shafts, if needed. Also, finding a shifter can be interesting.
