Since I have to repaint my fenders anyway when I add the AWR flares, I decided to add one of these Sparco fuel fill lids that I've always had my eye on. When I get the fenders cut and welded, I'll have them also weld metal to fill in the crescent-shaped gap around the cap. The challenge will be to come up with a way to support the cap from beneath yet sit flush with the fender. I plan to fill in the "Sparco" logo and have it all painted to match the car for a stealthy look. I'll post more pics as the project progresses...
