It's really really easy, Just undo all the bolts and screws, and lift it off. Sometimes the factory put in one or two spot welds at the front, but they're easy enough to pry apart.

Remove the bumper first, then Remove the headlight surround, then the turn signal, then just start taking out all the bolts that run along the top edge (the bolts closest to the firewall have some tricky clearance around the hood hinges.

Then open the front door so you can get at the screws holding the fender to the A-pillar bracket. You can either remove the big phillips screws (four of them) or you can remove the interior trim and undo the bolts securing the bracket to the car.

The fenders aren't that heavy, you won't need any help carrying them out. Don't be afraid to drill out the screws on the A-pillar bracket if you need to. You can get some more from the other side of the doner car, or re-use the originals from yours. Make sure you take all the bolts and screws you removed from the donor as well, you'll always manage to lose a few.

If you can find a rust free car the right colour, you can repair all kinds of damage really quickly and easily. I've got panels, door and lights from about a dozen different vehicles in my car.
