I have a complete never installed hood tach made by Dixco for the Chrysler parts counter. This has the correct steel mounting nut with 4 holes and the special U nut to tighten it. It also has the 2 special anti hood spin screws. Cheap repros you see on egag use a black plastic nut and black phillips screws to stop it from spinning. Install instructions and rubber gasket. $ 800.00 US funds shipped to Canada and lower 48 States. Pm me if interested.
