For the 94-98 200MPH speedos how can you tell the difference from a fake or a real one? I purchased one from a person i really trust but I want to make sure. Right now I don't have a car I can put it into and check. Anything internal I can look for?
They have been selling the overlays for years. They are pretty easy to fake. The best way to tell is to install it and check the accuracy of the speedo.
