I started by cutting off the roll on the edge of the boards, then drilled out all the rivets attaching the boards to the support brackets underneath them. I also drilled out the 3 rivets that holds the foot-well piece to the running board on each side. I got rid of the factory grip "bumps" with the drill as well. I then cut my sheet of aluminum so that I had 2 strips that were 6.5" wide and long enough to reach the end of my tunnel (can't remember the exact measurement at the moment). On both I cut the angle about 10" from the end of the board. I then slid the aluminum under the foot-well piece, drilled holes where the existing stock ones were and riveted it in place. To finished it off I riveted the angle aluminum on as edge pieces, and for a little support. That's as far as I've gotten so far. To finish up the project I'll be putting some ROX grips on and making some holes for snow removal.
Only issues so far are a couple rivets starting to fail, but that's what you get when you use Mastercraft rivets from Crappy Tire!

I'll put up new pictures when I completely finish them, but that won't be for about a month because of work.
