1. Jack the car up so the front end is high enough to work on. Place jack stands under metal sections of the frame. Safely lower the car onto the jack stands.
2. Align your chin spoiler in one of the following ways. Use duct tape to hold the spoiler in place.
- Choice A: Align the edges of the chin spoiler with the edges of the front bumper. This will cause the front of the spoiler to site behind the front of the bumper about a ¼ inch. This look is how the OEM Mach 1s came from the factory
- Choice B: Align the Center of the chin spoiler to be flush with the center of the front bumper. This will make the chin spoiler stick out a little further, and look more aggressive. However, the edges of the chin spoiler will not be flush with the edges of the bumper. (How I will be doing it)
3. Once the spoiler is held up with duct tape. Use a sharpie to mark the holes through the spoiler, onto the bumper cover.
4. You can now remove the chin spoiler from the car. Be careful and gentle when pulling the duct tape off of your paint.
5. Using your ¼ inch drill bit, begin drilling out each of the holes that you previously marked. Be sure to stop drilling once the bit has punched through the plastic. Also be mindful of any fog light wiring or intercooler tubing if they are located in that area.
