As the title says I want to replace the spoiler on my 2000 si coupe.
Two questions.
One: If I replace it with the lip style spoiler does anyone have any suggestions on how to cover the holes from the original? Can't afford a new trunk or body work on this one. Is there any discrete paneling of sorts to cover and seal them.
Two: Anyone know where to get a lip style spoiler that will fit the original mounts? One that isn't gaudy or extreme overkill anyway.

Thanks

And I'm not sure why in the heck I put this question in the tech forum. My apologies.
