Hey, this was my year, guess I could shed some light on it. Here's probably the best pic that exists of the bumpers. Basically move the front and back lateral 1x1's to the ends of the frame to define the frame perimeter. Then we used 4 bumper sections with 2 1/4-20 studs each and wing nuts to hold them in. It definitely wasn't the best system, and 548 has used one piece bumpers instead since then.
