I was going to fab and form a new floor pan for mine. Bought the metal, cut a 3/4 inch peice of plywood to use as a form complete with all the holes I needed, put it in the truck to make sure everything fit and the holes were in the right location and then it dawned on me, why bother with a metal one. the plywood is very sturdy and probanly insulates against heat and noise better. I used 1/8 aluminum plate for my M/C and battery covers by recessing the edges of the holes with a router 1/8" so they fit flush with the floor. worked out excellent.
