I installed the original 195°F thermostat and with this water temperature, the air being drawn through the radiator gets much hotter and the bimetal spring of the fanclutch actually goes on full blast.

If the cooling system does not do the job, a colder thermostat does not help, its just ...

In 2014 I bought a brand-new compressor from this board's sponsor, for my 1988 truck; compressor came with PAG oil - tested a drop of the oil at work. Since I was staying R-12, I dumped out all the PAG oil out the low'/high ports, added a few oz. R-12-type mineral oil, turned the compressor drive ...

What most likely happened is you had what is called ‘seasonal’ losses from the comp shaft.
The correct approach would have been to have a pro shop use their RRR machine and pull out what refrigerant was left. Then have them install the correct amount, which is usually on the under hood sticker ...

I think I'm a little overcharged at this point but the high side is only 10-20 psi high . It still cut out at highway speeds. I jumpered the low pressure switch and now it cools properly at highway speeds.

You mean 10-20psi higher than where you think it should be? Jumping a switch except for ...

My 1988 Mazda truck runs an evaporator and a compressor from Tim ackits.com

I saw a video online where a guy had a listening wand of some sort.....anyone have an idea where I could purchase one? Has headphones and a wand, so you can stick it down around the AC components to listen for leaks....

You could try a piece of rubber hose as a stethoscope.

And maybe try soap ...

This question comes up all the time. The new self sealing cans do not work well at *all*.
The pros here use a side tapping tool and we do not tap using the poorly designed gizmo on the top of the can. You can get such a side tapper here from the board owner, Tim.

Is this an instance where an older R134a can tap doesn't work on the newer "self sealing" R134a cans? I've read to
...buy an inexpensive adapter that goes on the can
...turn the existing valve all the way down, then to back off just a little
...use a can side tap
...buy a new style R134a can tap

88% of USA households now have AC.

When I lived in Pittsburgh (until 1967), only 1 home on our street - a fairly well-off area - had home AC. My parents later got a room AC unit about 1966.

Now I'm in Arizona, and Phoenix low temperatures can be 95F, and it can still be over 100F after midnight ...

The tech was charging by pressure, not weight.

That does surprise me, unsure why a shop would not have modern equipment.

If the AC cools you and your passenger: fine. Cross your fingers that your truck only had a tiny leak due to attrition over the years, or ...
