All the following should bolt up to the first gen V6 automatic transmission.

1992-2000 Mitsubishi Activ-Trak AWD t-cases


Short input or a clocking ring are required for the following:
23 spline Atlas transfer cases
Rock Trac NP241
NP242 with AWD Select Trac
NP231
STaK Tcases
Dana 300
Dana 20

Personally I think an NP242 out of Jeep Liberty with 4.1 crawler gears would be cool. It has fixed yokes, it would give a great low range ratio and AWD for those snowy days. Down side is it's chain driven.

There are also 2.85 crawler gears available for your current tcase but I am sure your already aware of this. An other option I have been looking into is possibly adding a reduction box between the tranny and tcase. Several companies like advance adapters make reduction boxes that will bolt in, it's just a matter of how many mods to the tunnel, drive shafts and frame would it take to get a reduction box to fit.
