Yes I make the fore mentioned kit
Even with the seams fully welded I still managed to rip them apart
The kit is twice as thick as the metal that the factory box is made of, pretty flimsy.
Bang all the seams back together, make sure they are straight and welda ll the seams for the boxes you will see the factory spots, you should also fully weld the upper brackets in this helps a lot os well. You will need a wire that works with galvanized since you will run into that with the factory metal and panels. If you are interested in a kit let me know
