Mach 1 chin spoiler install

I recently purchased one from american muscle. what a easy install and it looks great when your done, the first thing i did was to put a bolt in the holes at the rear of each side of the spoiler with the washers and nut, there is a slot cut in the bumper just in front of the tire, i slid the bolts on eachside into the slot to hold the rear in place, i then lined up the spoiler with the bumper to the correct position and drilled the very front mount hole in the center of the spoiler, after installing the center bolt and tightening it down some to hold it in place i checked my alinement and drilled the rest of the holes and installed the bolts, it took all of ten minutes and the car looks ten times better, i know most of us on here wouldnt have a issue with doing it but i though this thread might be helpful to someone looking to get one.
