Hello VW Fan!
Please take a look and order online at http://www.classiccult.com/vw/ a nos dash kilometer counter. I have a few different in white or black. Starting at 20 USD + worldwide registered airmail shipping from Germany to you is 10 USD.
It is very useful: After the tank is filled with fuel, you just roll the wheels on the counter to match with the speedometer mileage and you are on the way. You then compare your mileage to it and you know how far you have driven. Great!
