You have a job on there.
Front fenders - remove the head lights and there are three along the top from memory that you gat at through the hole, a flat at a time for the last one.
A couple down the front, below the head light, 2 or 3 from the engine bay, you will need to remove the air ducts. A couple from under the dashboard, and several small self tapping screws in the A post in the top half ish. There are a few screws/bolts holding the bottom of the fenders to the sills ( rockers I think you call them)
Rear fenders are easier.
Undo the door catch, I had to drill out the crews on mine, remove the Ali trim at the B post, and undo the nuts and blolts - drill them out as the replacement set contains everything. There are two bolts at the top front from the wheel arch and third taken from inside the car right up high near the rear of the wheel arch. The rest are all in the boot - sorry - trunk, you will need to remove the battery. Again, there are a couple of screws/ bolts holding the bottom of the fender to the rocker. After that, it should fall off.
Best of luck, I have to remove mine from the passenger side to work on renewing the rockers and the floor.
