"Why would you be measuring resistance? If you're checking to see if you
have a gauge problem, wouldn't you use a test light to see if you're getting
power to the gauge?

guage on an early car or specifically 67.5 2L?"
I think the gauge repairer is more concerned with checking the gauge
operation with the correct sender attached, i.e. operation and calibration.
I can see where he is coming from.
Modern [EFI] cars have this data freely available in the Workshop Manual but
Temp. [and Pressure] V Resistance for a 40+ Y.O. car is a bit of an unknown.
If I get enthusiastic, I might dig out my senders and do a wee bit of
experimenting.
The Temp. sender will be relatively easy to plot the characteristics to, the
oil pressure sender, Hmmmmm!
