Default GMT-900 14-bolt under a GMT-800 truck ?'s...
GMT-900 14-bolts seem to be more accessible when compared to the GMT-800 AXN axle at this time. What is need for this swap?

I understand that it is basically a direct swap except for the shock mounts on the axle. Is that correct? What needs to be done to overcome this?

Grinder and a Welder ?
In for details, ie track width, available BRAKE Backing plates, ABS sensors, and traction aid differentials for the 14 bolt semifloater.

You need a complete rear end assembly.
Correct, its a direct swap
Nothing, they will still line up.
