Thank you immensely No one I talked with knew what it was or for

 

[melsg5]

I'm asking if the picture matches what you have, does it?
I have a 1971 GTO, original family ownership and it does NOT use one.

 

[melsg5]

Is your car a 6 cylinder?
That is the only application shown using a thermal limiter the number as of 1983 was 6556440

I'm the second owner of a 1972 Lemans with the factory Frigidaire A6 compressor, and it has one. the socket it goes in is clipped to the top rear bracket that you use to adjust the pulley belt tension on the AC compressor. I always keep a bunch of spares in the front ashtray. They used to be less than $2 each 40 years ago. You should be able to find a replacement for about $10 at an auto parts store. It won't be new old stock though. The usual reason they blow is the Refrigerant level is too low.
