Cabby boot lid - US spec with 3rd brake light

Hi there,
I'm after a US spec boot lid with the hole for a third brake light. There is one on eBay at the moment (https://m.ebay.co.uk/itm/VW-GOLF-MK1-CABRIO-REAR-TAILGATE-BOOTLID-RARE-USA-RABBIT-3RD-BRAKE-LIGHT-/282367862343), but I don't think it's worth that kind of money!

Let me know if you can help.
