those aren't GT sideskirts, those are SE sideskirts
GT skirts are much bigger and have a door piece
hmm ok they were on a vert with a gt front
GT convertibles had different sideskirts than the rest of the GT Sunfires. Someone must have put those sides on that particular convertible because I've never seen those on a convertible. All convertibles had a rather plain flat looking set of skirts on them.
Either way those are typically found on 2000+ Sunfire SE's
