I thought the fender bolted directly to the "T" nut mounted in the rocker panel. There is a small "L" bracket at the bottom of the fender that attaches to the splash shield. There is a fairly flat bracket from the outer edge of the firewall, with a somewhat hidden ender bolt accessed from the door jamb area.
Can you provide a picture of the driver's side so that we can make sure we are clear on the part you are looking for?
