You pretty much have it right. The only thing that is harder for you is the transfer case. You should probably consider running a divorced transfer case - that is one that isn't attached to the transmission. I seem to recall that Nissan has a divorced case that could be used, or better yet get one of the Toyota cases and the kit to make it a divorced case. Then cut a hole in the floor for the shifter, and the rest is just like any other SAS.
