Nismo rear deck spoiler on 370Z sport coupe

Stevie Z

I own a 370Z touring coupe with sport option, I am considering replacing the stock rear hatch spoiler with the new 370Z Nismo spoiler. My concern is whether or not drilling new holes in the rear hatch is necessary. I do not want to drill holes and probably won't bother with it if I have to. Most Nissan parts reps don't know the answer to this question. One parts rep called a Nissan rep in my prescence and he stated that no drilling was needed and that after you remove the stock spoiler you utilize the existing holes to mount the new spoiler. I hope this is true, any feedback or advice would be greatly appreciated. Thanks in advance.
