Do shark fins for Mk 4 Boras exsist?

The sad story is I caught the antenna on a faulty auto closing garage door, destroying the standard mount and creasing the roof.

Creasing it just enough to mean it has to be repaired with the roof lining removed, which really means a new roof lining plus plus plus $

This simplest solution for me would be to fit a nice big shark fin over the top looks better anyway, hides the damage and makes it all waterproof again.

I know there are little one but they don't look as good and don't cover the damage.

and..

Every shark fin is flat, they fit the golf fine but the Bora has a very curved roof and I can't find one that fits.

Has anyone had any luck?

Or any suggestions?
