You would have to contact Ford. I doubt they have an original window sticker for that year of a vehicle but it's a good place to start.

The Monroney sticker is required to be affixed to the side window or windshield of every new car sold in the United States and can only be removed by the consumer (Chapter 28, Sections 1231-1233, Title 15 of the United States Code). Contact your local Ford Dealership who can get a copy with the Vin # of your vehicle, it may take a few weeks for them to get it from Ford.
