There was a gap at the rear of one of the side skirts and I can see that two of the black fasteners that clip into the yellow plugs are broken. I've removed the screws around the wheel arch and also removed the broken black parts (male) from the skirt. To remove I just slid (forced) the broken ones sideways out of their locking position on the skirt. I'm trying to do the reverse with the new clips but cannot force them in without damaging them. Is there something else that i should be doing to put the new ones back in place?
Thanks in advance
