This is a new voltage regulator with it's original box. It is Chrysler Corporation part number MD607372. It is marked as fitting some 1970s 1980s Colt models. I don't know the specific years and models applications. Please check your own parts listing to be sure of your specific application. This came out of a closed dealer's stock and, as with any vintage electrical part, is being sold as is. Buyer to pay packaging/shipping. Shipping price includes insurance (US only).
