A couple of notes to add. There is some things wrong with that video
The so called washers on top were panel anchor nuts and do not go on top of the fender, they belong on the black frame so don't remove them. If the fall off, stick them back on and bend the spring tab into the hole to get them to remain on.
The bolt behind the door doesn't need any special tools other than a 12" extension with a 10mm socket to remove/install it.
The black frame is what align and holds the fender in place. It has 3 10mm bolts that hold it on and it is critical that this frame get re-installed in the exact same location so you should use a black magic marker to trace around the frame on the bolts closest to the door and a gray magic marker to mark on the front one he left on as a pivot. All 3 bolts have oblong holes for alignment adjustments that are made at the factory. Using the marker saves you a ton of headaches when reassembly.
Also his wheel well liner was already removed, there are 4 or 5 7mm bolts that hold that on to the fender.
