well the back floor pan looks simple enough to figure out, how ever the front does not. The front one has this metal lip facing down, it forms the shape around the wheel well, where do i weld it to? The bigger question is, the old floor pans appear as if the section where the pedals go, are appart of the floorpan itself. The new one does not have that section at all, and mine appears to have some deep rust, is there another piece that i need to go and buy??
