Google Jeep JK fuel door on WJ. Look through the pictures until you see a JK door on a WJ and then open the thread/site and see what you can find. That same person posted on another forum and did a writeup that didn't have many pictures, but it was easy to follow. Shouldn't be too hard to figure out even without a writeup. There's also the much cheaper TJ fuel bezel mod, but it gets rid of the door entirely.Still looks cool.
