I finally got a chin spoiler from mustangtuning for my 97gt and it was expensive as crap, but hey I wanted one. Anyway are there any specific type of installation instructions or do you just line it up straight then drill small holes in the bottom of the bumper and push the pins in. It came with a good bit of push pins but there aren't any holes in the bumper and I was also wonder what size drill bit i would need that way I wouldn't make the holes bigger than need be. I'd appreciate any feedback.
