Crushed fiberglass rear quarter corner on Mclaren 12

[Vergis]

My friend has bought this car with damage to the rear drivers corner by the tail light.

The obvious solution is to find a good part and fabricate it onto the car. However , they seem all to be for the other side as luck would have it in the 2nd hand market.

Is there anyone that could rebuild the corner and has real expertise in the field?

Any suggestions appreciated.

Thanks
