I would ask the Owner (or Employees) of the junkyard ,
1st: If you can buy the whole thing? (That is if you have a place to keep it.)
If that is not an option (because some yards won't sell the whole thing)
2nd: If the cab is removed? Can you buy the complete frame?
If this is not an option,
3rd: Get the Transfer case 1st (while the axles are holding the frame up off the ground).
Then try to get the axles and steering gear in the same trip.
Then all the brackets (take a couple of cordless saws-all's)
And of course all the crossmembers .
Some-places will set it to the side.
And put it on stands for you.
If they know you want a-lot off of the truck.
Hope you can get the whole truck
.
