Engine swap idea

Since Mopar converters and flex plates already exist for the Jeep / AMC engine, it would be interesting to see how hard it would be to fab an adapter to a native Mopar transmission. Who knows? If you go to enough trouble (and luck) you could adapt a 2wd tail/ OD unit to a 4x4 main case. Even in the US, tho, 2wd OD transmissions are not very plentiful
