here's an upgrade (new rubi t-cases)
http://www.jbconversions.com/pages/products/nvg241OR/index.html

they (and others) also have 4:1 kits for 231 like teraflex etc ...  with 4.10s I am ok with 33's - if I wanted more gear I would do this before redo'ing axels ...

I believe there are some variations of the 231 in chevy 1/2tons with wider chain that use 6 planetary gears instead of 3 that can be adapted to jeeps ...
