I found some time in the garage so I managed to fix the boot handle and number plate light onto the boot lid. This involved measuring lots of times and lining the parts up prior to drilling. GD had already pre-installed a wire in between the boot lid skins and I managed to cut a hole behind the number plate light to enable fishing out the wire. I will fabricate a bracket to hold the number plate later.
I also drilled out the hole to accept the Aston Martin style fuel filler. I will properly fit it in the coming months.
