i got the floor and the small patch in the toe board done today.i butt welded the toe board in. i made my cut in the middle of the flange on the frame rail so the weld would not be seen in the engine compartment , the top weld will be hidden by the torque box. i used my hole punch on the edges of the floor pan,another one of those you need it tools.mine punches a 3/16 hole ,just perfect for plug welds. the floor went just perfect. nice and tight all the way around. i used a hand full of screws to pull it down tight then welded it down .even my welder worked good today. it made the prettiest welds ,nice and flat .just a light buff with my angle grinder and the welds were smooth.
