Need help with rear spoiler!

I have a 2002 3.8L Manual Mustang, and I was rear ended. My insurance company is taking care of my broken tail light, and my bumper. I figured I would use some of the left over money to pick up a spoiler, being that my mustang doesn't have one, so I did. I have a spoiler from a 2001 GT. They should be the same, since the car has the same body style, right? Either way. I really don't want to measure it myself with a grease pencil or whatever, I'm just trying to find some measurements for the spoiler. I'm aware that underneath the trunk lid there are 2 small rubber plugs that cover up the holes where the spoiler bolts should go through, however these holes are nearly 2" in diameter, and a bolt is barely 1/4"... So I want to make sure that my holes are drilled in the EXACT correct spot. If anyone has any idea on the measurements or where to drill the holes, please let me know!
