Well, I made a little progress this weekend breaking the bed down to its individual components. I'm thinking about going back with 1/8" diamond plate for the floor and wheel wells because the rust there is fairly extensive and I cannot think of a reasonable way to duplicate the original contours for making patch panels. Has anybody else used diamond plate when you fixed your bed? I can't seem to find any diamond plate wider than 5 feet and the original bed is 63 3/4" wide. How did you make up the extra 1 7/8" on each side, angle iron?
