I can give you a tip on installing the lengthwise stiffner and the attachment channels (all purchased from JC) that makes life easier. Cut the old ones off flush with the bent leg and leave that attached by its spotwelds to the board. Grind it smooth and then weld the new one to the piece you left. Benefits: exact fit in exact location, no burn through because board may be to thin. not noticeable when finished. You can see in these picks how I did it then I undercoated mine to make sure they last a while.
