Cabs are the same.

The main Difference is in the frame and 4x4 specific components.

Your ECU will not be set up for the 4x4 stuff so that will pose 1 small issue. Either use all the matching electronics from the donor chassis or have yours flashed to activate the 4x4 stuff.

You can use a floor jack and block up the cab and front sheet metal, then roll out the old chassis and swap in the new.

What ever you do Be very careful not to damage the cab/sheet metal.
