Yep, sideskirt will need to come off (and it's riveted on:dapprove

. Also need to take the black plastic off that is under the wipers to get to one bolt. Headlight needs to come out also.
Swapped mine for new one last weekend and it took me 4 hours lol. Worst bit was undoing the the bold that is just behind the bumper (took me about 45 min with one click of the ratchet at a time

), but if you take the bumper off 1st it wont be a problem.
