It's not hard to build your own, though MJ rails have a few challenges to them. namely the frame is sheetmetal, and many of us don't really have any pinch seam left to supplement the frame mounts (plus the pinch seam doesn't extend past the cab). I worked around both issues by drilling holes through the frame and pushing the stringer bars through and welding them to both sides. I've dropped the MJ on them. :D I tucked my in to the body as much as I could, but you could extend them out more for use as a step. oh, and if you weld, be sure to use an adapter plate so as to spread out the load on the sheetmetal.
