the transition case with the 2.313 gears has the same identical attachment 5-bolt pattern to the tranny or adapter, and the 10-spline input is identical as the 73-older cases as well.
IIRC, the only difference in the 5 attachment bolts was the thread pitch. (WHY, I don't know, but it is....)
I believe AA makes adapters for both, either way I'll bet it requires replacing the tailshaft of the tranny.
Buddy of mine runs the manual lockup switch and loves it. I'll wager cruiserrg is the expert on it tho....lol
