If they are not what you are after, get hold of a broken speedo, and dismantle it, then take it to a sign writer who can do digital printing... I have just had this done and it looks great the only thing is that my beetle is a 1500 so the gauge is different to the one your'e after.
Here is what I have had done any way.
