I took the 4" oval Ford factory tube steps off my 2003 F250 last night. The passenger side ran over a rock and damaged one of the 3 brackets on that side, but the driver's side is in great shape. Both of the tube steps are in good shape. Great replacement if you've damaged the driver's side on yours. Asking $25 for both steps, all 6 brackets, bolts and all hardware to mount to a 99-2004 (I think) F250.
Here's what the driver's side looked like before I took it off last night


Here are the two of them in the garage and you can see the one bracket that is bent. With some heat and a good vise you may be able to bend it back into shape.
