Thx for asking
The plate is B5 license plate bracket. I bought it from a vw vortex member for $20.00. Search the web, VW/Audi forums as they are cheaper.
The license plate clear cover I got it from wallyworld. To install clear cover to license plate bracket, I used 4-2" L no.8 or 10 stainless pan head Philip machine screws, 4-no.8 or 10 stainless nuts, and 4-2" no.8 or 10 stainless oversized fender washers.
I placed the fender washers behind the two horizontal slats as you can see from the picture no.2 above.
