i would draw you something up on paint or look it up but it wouldnt be hard at all to do it the way im thinking it was exactly what pumpkintoy said. I would just get some tubing same as what you have cut a section out and build it up and around sheet metal it so its fenders, thus taking maybe 3 hours and will look clean. Then you can deck up to it and in front of it utalizing all the space. think about a regular bed you have wheel wells in a bed and sides, granted you have a shorter bed space but dont most of us? haha just something to think about. Also like pumkin toy said if you don't care how it looks then go for it I just think you may regret it in the long run.
