I mounted these on my 2004 Tacoma 4WD truck. At first I tried to use the old Toyota flap as a guide but then I realized all I needed to do was hold the Dee Zee flap where it looked right and lined up with the two existing bolt holes. I marked those holes and then drilled a third hole to secure the top neck of the Dee Zee. It was easy once you make sure your holes are drilled correctly: use a piece of cardboard to create a pattern which you overlay on the Dee Zee. (In fact, you could make a pattern out of the cardboard on which the Dee Zee comes attached.)
You will need to turn the front wheel in order to drill the third hole, but it wasn't hard. I'm not sure about the rear wheelwell. You might have to jack the truck up and remove the tire temporarily: yes, a bit of a pain but worth it, considering how much Toyota wants for these flaps (over $100 each).
The flap hangs down sufficiently to keep mud off the truck. it's maybe 2" shorter than the Toyota flaps--but those are so long, they get ripped off when you back over a rock (which is probably why you're buying new flaps, right?). It also extends about an inch outside the edge of the wheelwell--not quite as far as the Toyota, but sufficient.
