The "Body Name Plate" is attached to the top surface of the left air duct cover, under the hood, near the cowl. It can also be found in the front driver door jamb on some years and models. The name plate carries the style number. The first 2 digits represent the year, "66." The last 5 digits indicate the vehicle style. Use this style number along with the table above to identify your model.
