Spoiler attachment (again)

[Wimmy]

I'm not sure if IU have a couple of pieces missing from my spoiler. I basically have the spoiler and two legs. The legs are flat pieces of plastic. Looking at other pics of the spoiler, it looks as though two eliptical shapes should be attached to this to bond to the window.

Can anyone confirm/deny this ofr me? I am unsure if the one on the pic has been made specially.

Thanks
