I have 4 clear lense headlights for the 1983-86 tbird/cougars. I am not sure what original application that were used for but they do fit the square headlamp bezels. I will warn you that some modification to the header panel is required to make the bulbs fit (there is a larger casting of plastic on the back of the light that interferes with the header panel. By simply triming the header panel with die grinder, this problem is fixed.)
Price is $60 for all 4 which INCLUDES shipping to anywhere in the United States.
