I pulled the flange to see if it indeed is the same as a 4x4 version. It is. The output spline is 29. I also took a spare 4x4 case just to "be sure" and it bolted right in with plenty of spline engagement. So yes, 2wd and 4wd G56 transmissions are the same. And, 2wd and 4wd dodge crossmembers are interchangeable.

And in, but its not staying. Nice to know a 4x4 conversion wouldn't require a trans change.
