I happened to see this old Ford while out for a walk Monday.  My dad always told me if you looked at the plastic over the tail lights a model year would be designated, however.  Some years the tail light configuration didn't change from a previous model year and the stamp also didn't change.  I posted this to my Facebook page and asked for guesses on the model year.  My guess is roughly 1966 but I've a 12 year range of responses.  It may not be the most important post but the responses are tremendous.  What is your guess?
