What was the code for the vinyl top on a 73 challenger? The reason for asking is I received my fender tag from the previous owner today and it has a code of V1X and from all that I can find out it is a vinyl top code but I have never seen a 73 with a vinyl top. If this checks out as a vinyl top car I will put the vinyl on it even though that is about the only thing it will have that it left the factory with other than the Bright Red paint.
