For shaping, I'd use strecher to strech the top long edge. I'd use thread-riveds with gaskets. You need to drill holes for them but before installing the rivets, use a pressing tool both sices w/center bolt to make a little recess so that rivets bolt would be flush with the roof surface. Then make the same recess to same place to rails so they will fit perfect.
We made one off those to one track race car way back ago and they came wicked and nice. I think I dont have any pictures left from that. They went with my last computer crash. Now have everything at harddrive.
