I'd either leave them as they are or paint them black...
- did you use the item number when you called in?
1. Kaminari does sell the grill that you see on their car.
2. The part number is: K0GRILL (-the second character is a zero.)
3. Go to the order page on Kaminari's website, direct link: http://www.kaminari.com/order.htm
Fill it out
4. You need 3 pieces if you have a full Kaminari kit
5. Each piece is $40, add $20 for shipping.
6. Call the number on the bottom of the order page to confirm it, and give them your credit card number.
