Keep in mind the running boards set about 4" or so below bottom of cab, also front fenders will hit before your frame hits. all you need to do is get your body on there and moch it up then see where the rest of frame and your body mounts will go. You'd be surprised on how little of a notch you'd need and how low you can go without modifying too much. its not like a car where you have to channel it over the frame.
