Screw for Xbox 360 Steering Wheel Clamp

[Marmite]

Bit of a random one this but would massively appreciate it if someone has one they aren't using that they might be happy to donate or perhaps take a small fee for?

Image of the bit i'm after can be seen in use with the clamp here: http://media.teamxbox.com/xbox-hardw...1148169850.jpg

Thanks for looking.
