[Request] Opel Corsa-D 3 Door Stealth Shelf

Hi guys just wondering if anyone here can help me find one of these or recommend where to get an original one modified

I have spoken to these guys on the phone & they tell me even though it's still advertised it is no longer available

The genuine shelf looks like this



I need to fit 6"x9" Speakers into this shelf, the exact ones are here

The bowl / indent character of the original shelf doesn't allow room to fit these speakers so needs to be flattened or made a different shape like in the advert above

Thanks in advance for your help
