coolant temp location on 62 Cadillac?

I bought a new coolant temp sensor for my 62 caddy fleetwood and have no idea where it's located and my manual doesn't show it. Any help is appreciated!

What engine...??? Does it have a center manifold mounted A/C compressor...??? If so, it's under the compressor...otherwise it's in one of the heads.

390ci 6.4l...yes it does have A/C and the compressor is right up front.

 

Driver side head right up front, inboard...

 

Thx
