i don't think it will fit without some modification, i believe the newer trucks have a different frame width.
If it has disk brakes, it most likely has the drum in hat e-brake as well, small drum shoe brakes inside the center (hat) of the rotor.
Not really gaining any strength by doing the swap either, most on here will tell you, if you're yanking out a 10/12 bolt diff, you should be upgrading to something alittle more beefier.
but then again, it's your ride, your labor, and all depends on what you plan on using the truck for.
