Just installed mine a couple of days ago... the clips, hands down, were the hardest part of the job (only because I removed them so I could save them - doh!) if you pinch the corners on the square part inside the liner by reaching in through the hole that goes to the air box, and then rock them back and forth out from the bottom you can get enough of them to start, then get the rest of them after you cut your nice big hole in the side - then repeat the process with the clips further toward the rear. I was helped a little by having the second battery tray where the blower and washer used to be. In retrospect, I would have just used wire cutters on them and replace them had I gone out and bought extras. My biggest mistake was dropping the wrench inside the fender well while tightening the bolts and having to remove the whole mud flap assembly... I did this twice!:bash: The rubber connector wasn't much fun either... but I think the job would have took less than two hours if it weren't for the durned clips.
