And to give you some encouragement, even though my car was an original "black plate" car from CA and every nut and bolt came off clean with the exception of one - I ended up replacing both front fenders and had the passenger door reskinned. There was a lot of bondo under the cheap paint job (interesting the same shade as your car) and enough debris had collected between one fender skin and the rear reinforcement brace to rust out a spot from the inside. The passenger door had been caved in, drilled and bondo'd and the other fender had been hit at the wheel well.
