Big Chev 3600, thank you very much for the response. I think I should have been more specific in my question. I'm looking for a thermo switch that is a common auto parts store item that is either in stock or available by special order so it can be easily replaced in the future if necessary.
There is actually a male 1/2" NPT to female M16 x 1.5 adaptor that I found on, of all places a beer home brewing forum. That would be an option for me if I can't find a pipe thread thermo switch and have to use one with metric threads.
To me the quest for stuff like this is part of the fun of the car hobby.
