Don't know if thats the right word for it, but there were two plastic flaps covering the bolt mounts for my 2001 WRX Wagon's rear spoiler (one at each corner).

Only one has gone, presumably been snapped off??

Any ideas where could I get another one? Could try making one and spraying it Silver, if it comes to it... pain in the ****.

Someone snapped the rear spoiler off my old Cooper S a few years ago - £220 replacement - that just left two horrendous "bullet" style exit wounds on the roof.

I must be jinxed.
