I DON'T want to use an electric gauge either, so please don't recommend that thanks.'

Most Mechanical gagues and sender have a very large sender (thread are like 3/8 npt, which is like 3/4" in dia) not sure if it would be safe to drill and tap the passenger head for it.
If you use one of those wierd adapter, it would most likely stick out pertty far and not give very accurate readings.
You can try the water pump or even a Tee in the radiator hose. But you would be reading either inlet or return water temp and not engine/head water temp.

I drilled my water pump, on the hot side that exits the engine. I'll bet that it reads a couple degrees cool, but I'm sure its close.
you can just see the AutoMeter temp sender and wire under the top rad hose.

We have no idea what your sending unit is like. I apologize for not being omniscient. You must have missed the part about searching.
A search for "mechanical temp gauge" returned most of the other items referenced here faster than waiting for a reply.

Stupid Question? What is a mechanical water temperature gauge? Would this require the use of a thermocoupler, with a molded wire extention coming out of it, to the dash gauge? Or are we talking about a mechanical water pressure gauge, with 1/8" plastic tubing, to the gauge? Thanks

I bought a cheap drill bit & tap ($19 delivered), then drilled the existing hole to the rear of the passenger head. A new Autogauge 17/8" gauge was won on eBay for $27 delivered. Yes, for safety's sake, I did remove the head to make sure no filings remained, and I did replace the gasket ($24).
