I recently fitted rear ones on my car. Sorry no pics.
If you're talking about the rear mud flaps, you don't have to drill any holes and nor do you have to take your rear wheel off either!
the instructions are a bit dodgy but re-read it a few times if you're not sure and use a lot of common sense.
Ideally, if you have a very short stubby type of screwdriver then that's best as there is just enough room for you to screw the screws in. alternatively use a long handled one but you need to angle is slightly reaching under and behind the wheel itself... bit awkward but doable.
Agreed the instructions are pretty rubbish, they only show diagrams, the rear ones are much easier to fit then the front ones, cause you have to remove the wheel, well i found it better too..
I fitted front and rear ones to mine, bit fiddly but once u get the 1st one on next ones are easier..
