You cant unless you modify the pan, the AWD blocks have holes for either the RWD pan, or the AWD pan. Where as the RWD blocks only have the holes for the RWD pan. Also the oil pickups are in different spots between the two blocks, and I didn't feel like tampering that much, and my front CV's were broken anyway.
The motor bolted right up to the tranny, dispite half the people on the internet saying it wouldn't. Aside from that, I had to switch the motor mounts from the AWD block to the RWD block, took the front prop shaft out, removed the CV's, but I had to hack up the CV's afterwards to keep the splines just attached to my hubs, had an issue with the bearing coming a bit loose.
At the end of the day, it was a cheap and easy fix to my problem, and ended up with a motor with 90,000k on it that runs beautifully! Hopefully if anyone else encounters a similar issue, this will help them!
