ECS Automotive makes the most correct version I have seen, if your car came with one originally. It is called a Conformance Decal and was just a government mandated decal that showed the date of manufacture and the VIN and in some case weight of the vehicle.

You have to call them to order the exact model and you need your data for them to make it.
