Yeah, make your own ... and that SD cage is worthless ... I'll be right over to pick it up
Seriously ... by the time you modify the SD bits to do what you'll end up wanting, don't you think you'd be time ahead using them as a template to make a copy from that you could modify for racks, awnings, lights, etc. as needed.
Presuming that the SD comes powder coated (I hate that stuff), you'd need to remove it as mods took place and re-coat with something when you're done anyway, right?
