Bought my first rare "SS" B body this weekend. :)

My mom had a '75 Fury, same body style, during the mid '80's. They are nice driving cars, especially on the highway. Her car had some kind of vacuum operated switch hooked up to the driver side fender indicator light. It would come on when you were driving "enthusiastically", to let you know you were not getting optimum fuel mileage. Whenever my dad drove it, the indicator light stayed on most of the time.
