Have a look at Lakin plates: http://lakinplates.com.au/index.php?...55_108_571_880

Lakin make excellent products and customer service is spot on. Alot of GTI and R guys have the Lakin front plate brackets to replace the horrible piece of plastic VW gave us.

You might need to email them and ask for pics of a bracket fitted to your model Beetle.

Another (cheaper but effective) option some people use is double sided tape.
