Looked at the instructions ( a lot). They show marks under the truck lid where you drill. They say to scrap away the paint to clearly see the marks. However, all I see are small bumps. After scapping, all I see are shinny bumps with no clear outline of the place to drill. I don't want to make a mistake and have an oversized hole or worse a hole in the wrong spot.

Q - How do I determine the exact center where to drill for the spoiler?

Need to know today - Thank you for any help or advice.
