I just purchased a new 2005 Rav4 S but it didn't have the spoiler. I've ordered one from Spoiler Depot which will be ready in a week at about half the cost Toyota wanted. In looking at the back door, I see I will have to remove the plastic around the top of the window to drill the holes to attach the spoiler. My question is do these plastic peices snap in and out and will I need to pry them out with a scew driver or will they break doing it that way? I don't want to spend $150 for installation. Any help would be appreciated.
