Their is a unit that fits on the package shelf, drivers side, very rare. will get a pic of the unit with a ford box and part number, I picked up a used unit at a swapmeet the spring. will take some pic's and send along. It will be next week. Also in 67 their is a unit that sits in the center of the shelf, not easy to install as the speaker holes are diff on the 65/66. Both take air from the interiour on one side and blow on the glass on the other side.
