Sunroof winddeflector clips

[Slugsie]

Just bought a sunroof winddeflector off ebay, it's the official Toyota one (at least I think it is, had Toyota written on it) with the little foldy flap in the middle to direct some air into the car. However, it didn't come with the 4 little clips that actually secure it to the car.

Anyone know where I might get these, or maybe have some spares sitting round doing nothing? Or, failing that, could someone with the same deflector take a couple of pictures/measurements so I can make some up?

TIA
