Mach Chin: Easy to install and they really clean the bottom lines on the stang. A must for every pony. Mach Side Skirts: No, Ford does not make side skirts for the Mach, but if they did they would probably look like these. I spent about $30 on the: 4"x4"x74" pvc fence post, pvc primer and cement, fender washers, sheetmetal screws, and some black plastic paint. After the cutting, assembly, shaping, painting and install, I've got about 4 hours into it. They're about 2" high leaving about 4" of space to the ground. IMO they didn't turn out too bad and all I was looking for was something that would go along with the Mach chin.
