I WILL OFFER FREE USA SHIPPING BUT ONLY WHEN THE BUY IT NOW OPTION HAS BEEN USED TO BUY IT. I have up for auction another of my good used and TESTED Gentex automatic dimming rearview mirrors. These are simple to hook up only a hot and a ground and you are in business. All 1989  - 1990 Ford Thunderbird SC Super Coupe Mercury Cougar XR7 owners replace the worn out tilting mirror with the headlight sensor with one of my automatic dimming mirrors. These are a direct replacement for the 89-90 Thunderbird SC / Cougar XR7s. These mirrors will work on all of these: Ford ,Mercury,Lincoln,General motors,Chevrolet,Buick,Oldsmobile,Pontiac, Dodge,Plymouth,Chrysler,Muscle cars, Hot Rods, Street Rods, Lead Sleds, Pick up trucks,Bronco II, Mustang II, Explorer, Ranger, S10, Blazer, The mirrors will work on any car or truck, SUV, Boat that has a windshield and a battery. These mirrors turn a real cool blue/green color when it sees headlights from the rear. The automatic dimming mirror you see here may not be the actual mirror you receive but they are all very similar no matter which car they came out of. They all take the same type of plugin on the back no matter who built the car. Please check out my 2233 feedbacks and see that I sell great used parts and I have a great record of fast shipping and fair shipping charges. I also send along a section of wire harness with the plugin for the mirror. If you have any questions please ask before bidding. Thanks ,Don[616]745-4430 djkerridge@hotmail.com
