2008 F350 4x4 Dually rear axle ?

[emilio]

I bought a 3 inch lift kit from Rough Country and was getting ready to add a rear block and found that the none of the ubolts that came in the kit were wide enough or long enough. I ended up taking one of the stock ubolts down to the spring shop and had some made. So what type of rear axle do I have? It does have LS and 3.73 gears.

Ok I think its a Dana 80. The srw f350 came with 10.50 sterling axle. I dont think duallies came with 10.50 rears right?
