I bought a different spoiler from Mustangs Unlimited and it was crap. Arrived busted and you could tell the poor quality. This spoiler is high quality. The ONLY complaint is that no installation instructions were provided. WCCC provided "some" help but instructions with pictures would have been much better. Note that it is heavy, thus the trunk would not stay open even after I adjusted the torsion bars to the max tension. Have to use a trunk pole to hold it open.
