Bumper reinforcement beams

I decided after looking at the condition of my bumper beams that it was probably time to get new ones, on top of that they interfered with my exhaust system and I wanted to enlarge the radiator supply through the front bumper so that one had to change as well. Instead of using thin steel on this I figured on going with 1/8" thick alum, should be a little stronger, also it turns out that each bumper will be about 4lbs lighter over stock. The front bumper hasn't been formed yet, the setup of the bends are a little tighter than the rear bumper and due to that the bending order has to be very specific.
