There is a sheet metal bracket that has three 6mm studs and 10mm nuts holding the bumper cover flange to the fender. With a little rust on the studs, these nuts are a challenge. Patience and penetrant spray are your friends. If the studs break, I was able to still buy the bracket with studs new from the toyota dealership 5 years ago. Once that is removed along with wheel liners, and underbody plastic, you can slide fender out.
