is it loose at the top of the skirt, or underneath?
if the top, you want #5 and #2, but most likely #2 is still there in the body. how it works is that #5 actually snaps into a channel in the skirt, and then that plugs into #2, which sits in the body. what you don't want is for that channel to be broken in the skirt - then you either have to live with it, or replace the skirt.
