hi everyone
this is the part where i tell you what an idiot i was, again.  hindsight being what it is, this is what i learned about my "overheating" fiasco.
the bottom line is that it was not overheating at all.  in fact, it wasn't even getting hot.  i should have thought that the fact it (the guage) made it made it to 240 so quickly was fishy.  too, i should have understood the significance of the nearly simultaneous "peaking" of the gas guage.  the thing is, the gas guage moved so quickly to that position.  the temp guage took almost a minute.  but it is that they were both doing it, that should have alerted me.
i bought an infra red temp sensor, and started the engine.  the temp guage rose to 240 in about a minute, and the front of the head, next to where the temp sensor mounts was reading 115.  that was the first time i actually let the temp guage keep going without turning off the engine.  that's when i noticed they were both pegged.
it seems that when the gas and temp guages aren't functioning properly, either they both go all the way "off" (the exteme left) or all the way "on" (the extreme right).  that they were the same was the clue i missed.  i thought my car was about to overheat.
i removed that little electrical thingie, cleaned all the contacts, including where it mounts, and re-installed.  voila.  guages that work.
i drove the car for the first time today, in about 6 months.  i blasted up the 110, and back down.  woohoo!
it runs great, and never got above 190.

thank you all for your help in trying to diagnose my non existent over heating.
