It is not too hard to cut the frame. There is a straight section of rail behind the cab that you can take the excess out of. I ended up whacking 7" out of mine before welding it back together. Lots of measuring to keep it square, weld slow, and reinforce the weld. This centered the wheels in the fenders pretty good.
I have seen a couple of trucks with late model 1/2 ton step side beds. They just do not seem right to me. I am going to rework an original 1/2 ton short bed that I picked up for $100.
