Raise the transfer case?

[rjstj]

I was looking at my truck last night and was wondering if anybody had ever tried this.
On Jeeps it's pretty common to raise the motor and transfer case, when installing a 1-2" body lift and fitting a flat skid plate under it all. Has anybody ever done this with a 67-72 4x4? I would imagine it would require CV drive shaft's but it would add alot of ground clearence under the center of my long bed. I realize that the center of gravity and all that would change but it would look nice and clean.
Any thoughts?
