I had my wing off for about a year and just recently put it back on...For the holes, I went to the dealer and got some of the interior molding "X-mas tree" looking plugs that hold the pieces to the car...they gave me 4 of them for free, but I think you can get them at autozone also for a minimal price...then I just siliconed the underside of them so they wouldn't leak...worked great for the time my wing was off...
