It looks pretty rusty, not all the way through, but in some spots it looks really close. How hard is it to replace this well? Since I will be turning this into a track car what about cutting it out and patching a flat piece of sheet metal over it?
Also there looks like a hole near the driver side rear of the tire well, a drain hole? Well its actually not a hole put a "flap" of metal cut in a circle with about 25%? connected. Is this always there?
