This is a NOS Ford thermostat housing which is correct for all  1969 1970 1971 1972 1973 Mustang, Fairlane, Falcon and all other Ford cars with the 302 and 351W engine.   All original Ford NOS and comes in the original Box with the plug.   Please note this one has the service replacement casting number on the bottom where it can not be seen.  I can assure you that it is NOS Ford of the highest quality.    I have had this stored in the garage for many years, but no longer, as it needs to go to someone who can use it. Would look great on a show car.  No import repro crap here!
