All you need is a holesaw cut a hole. Any dremeling will be done to the plastic piece behind the headlights in 04+ cars if I'm not mistaking. That's what model year you're talking about right? There's threads on here lookup RedDawnGXP's work pretty sure it shows you exactly how to do 04+ models and I've provided more than enough information to show guys how to do them on 97-03 gp's. If all fails I can do them for you but you can probably save a lot of money and mount them yourself.
