Yep, can be done. You will have to cut off the front bed mounts and lower them for the rear cab mounts and the gas tank doesn't clear, so you'll either have to put a tank between the frame rails in the rear or cut out a section of the back of the cab and re-plate it so the tank clears. Seems like there is a floor support that runs crossways under the cab that may interfere with the t-case too if you're running duals. Another cut and re-plate or a body lift. The body lift would help with the gas tank too, but i'm not a big body lift fan.
