I have been told that this is for a 1975 only Jaguar xj6 4.2 inlet housing with thermostat housing and appear to be in useable shape except for the top shorter flat hollow piece that is cracked  from freezing? that can be seen in the photos. There is some corrosion where it meets the head but look ok around the water jackets but please look at the photos carefully and ask questions if any and do your research because you are buying this as is and no returns and US buyers only please.
