Josep : As Richard noted, the light to which you had the link, is frequently available on Ebay, in its original (not Repo) Ford form. These were available through the Ford Dealers' Parts Counters from 1962 until well into the 80's. Ford actually reissued this part in the late 60's or early 70's, and not only kept the original Part Number noted by Richard, but also kept the original 1962 Copyrighted Instruction Sheet. The only change in the actual part being a slightly different shade of paint (the original issues were more "greenish", while the later ones were more "grayish"), and a slightly different cutout in the cover for the bulb to shine through. The original issues also came in a red and white Rotunda box, while the reissues were in a blue and white Ford box.
One other small item while discussing Factory versus Dealer installed items; Typically, "Options" are considered as items that can be ordered with the vehicle, and installed at the Factory when the vehicle is built. "Accessories" are "extra" items that could be purchased from the Dealer, and be installed by the Dealer, the Owner or the Owner's Mechanic, after the car was delivered to the Dealer. To add to the confusion, there are cases where Dealers have added Accessories to a car after it was shipped to them, and before they put it up for sale. This has brought about comments like "It must be Factory Original since I bought it new from the Dealer this way". To further add to the confusion, there are many items that were available as both an Option and an Accessory ; Power Brakes, Power Steering, Luggage Rack, Floor Mats (in 1967 as part of the "Protection Group" along with License Plate Frames and Door Edge Guards), Radios, etc. Dealers could add any of these "Accessory" items to make a car more desirable to prospective buyers.
Just thought this might be a good time to take care of a little "semantics" for future Posts.
