Problem with another "used" axle is you can't be sure your going to end up with anything better then you have. The D70U in my crewcab is in need of a rebuild, I'd rather spend the money on the rear diff I have, then I know for sure it's in good shape.
You could have a Dana 70 U, or a Dana 70 HD. Look at your diff on the front side, driver side upper rib front he center section, down to the axle tube. There is a casting in the case that tells you what diff you have.
