Unless you have a GTS4, with all the AWD gear, then a GTS4 manual box is a waste of a good AWD box. I'm pretty sure that nearly every previous question about this has resolved that the floor pans are different, and the RWD floorpan can't accept a AWD gearbox. And chopping the transfer case off the AWD box is, as I said, a waste of a perfectly good AWD box.
