I made mine, I posted in your "why I need paint" thread, I just some 6x6x3/16 angle iron with some 1.5" DOM welded on. I built them so long ago, I no longer have the pics. If you don't have access to a bender, you could make the step (if you want one) out os 1.5x1.5 square tube, would be easier to just mitre the ends and build the step that way.
Measure from one side of the jeep that you want to protect, muliply by 2 and then add another foot or so and thats what you will need to order.
