Went to the junk yard, and bought a spoiler for $75.00. I had a choice, taking the spoiler from what looks like a 97 200sx, and a newer 200sx, the year i don't know. I noticed that the light section on the spoiler looks a little different. The newer one was thinner, while the older style a little thicker. The trunk lid looks the same,...my question is, can someone give me some advice on mounting it, drilling the holes etc...

Thanks
