Post up your info from the FSM that states the the tail cone is the OD unit, I'd love to see that.
The OD unit is detachable, for 2wd the unit just has a longer tail and will just connect straight to the drive shaft.
The difference for 4wd is that the OD unit is exactly like it would be on say the AW4, the transfer case just connects directly to it, and you know the rest.
It make sense to me because I've actually seen it, just read some threads about 4wd swaps for the ZJ, it will show you everything.
And here is the best screenshot I could get of it from my FSM, sorry for the size.
