10" OF LIFT = BIG MONEY TO GET EVERY THING WORKING CORRECTLY !
forget about any stock length front drive shaft , IT WONT WORK AT ALL !
you are going to have to git one made from some one that knows exactly what they are doing ! and you may have to get the front pumpkin cut and rotated before one is made !
not to mention about the crossmember issue might have to be addressed before the shaft can be made ! IT WONT BE CHEAP TO HAVE ONE MADE , thats why you see a lot of trucks without one as they dont think about it till after they have the truck lifted to the sky !
