In VA, the state police handle things like this. I have found them very supportive of car enthusiasts. There is no need to try sketchy ways of getting VIN tags as long as you have documentation of purchase/ownership and contact them -before- you proceed. They have helped me remove and replace VIN tags for a restoration, use a vintage VIN tag that did not come with the car, get a completely new VIN tag, correct title errors (transposed VIN numbers), and so on.

They aren't after the average car guy, but are looking for criminal types who engage in VIN fraud. The key to success is working with them, not trying to slip something by them.
