how do i take off the fenders? 73 duster

Yup, and there is also a strut from the lower front part of the fender to the bumper bracket. There is a bolt about 6" up from the bottom rear of the fender inside the wheel opening along with the two at the bottom of the dog leg. I'd pull the rear splash panel before anything. It will give you more access to the upper rear nut. If you can get the door open just right, you can use a 18" extension, u-joint, and a deep socket on it.
