AMC thermostat housing, part # 3210852.  Note picture:  there seems to be a small area with minor issues, other than that it seems to be in good condition.  After researching the part number, it would be from a 1970 AMX or Javelin V8.  Might fit other AMC years and models.  I am doing my best to research the part numbers, before listing them.  I am going through several cabinets in the garage with different AMC parts and as I identify parts I am listing ones that actually can be shipped.  Please ask any questions before bidding if interested.  Only ship to the lower 48 states.
