trying to source a part?!??

i recently aquired a very nice mk2 vrs. however i recently noticed whilst cleaning around the engine bay that one of the rubber covers from the back of the headlight is missing!!:confused: i have enquired with skoda and apparently this part is not available separately,therefore i will have to buy a complete new light(very expensive).

i have tried various breakers online and e-bay without much joy so thought i would see if anyone on here has any ideas or even better the part in question.
