Best way to do this (and easiest) is to find a simular model with a
automatic in a bone yard. Splines will likely be different on Tcase
with automatic so if you be easest if you got a automatic and a tcase.
As far as trannies, you want a THM 400 that was used until 79 in Jeeps
or Trouqe Flite from 1980 one for a Jeep. AMC standardized bolt
pattern in id 70's so any tranny from a 6 or V8 will bolt up to
engine. THM 400's were ouly used with Qtrac Jeeps so if you use a
THM400 for this, you will need to change the output shaft on it as it
is too long and no adaptor is going to fix that. If you want to avoid
shaft swap , use a 80 or later Torque Flite.
