I took in a piece of 1" x 1/8" thick (I think) aluminum that I bent around the body of the Jeep. I left enough on the one end to get to the tailgate opening and just told them how far to take the other end. I then cut out my wheel openings where I wanted, along with the door opening. I just had them do it in the height of the Jeep body. I essentially had them build me a full length body armor "blank". Hope that makes sense.What kind of drawing do they need at Metal line to do something like that?
