I have a new repop GM 81 oil pressure gauge, # 25025147. I seem to recall you saying the resistor is built into the new ones. Is this correct, or is my all timers accelerating?

good point... 
For some reason I had temp gauge on the brain.
Same deal though, all reproduction gauges have the resistance built inside of them. All cars 1974 and newer used a mechanical oil pressure gauge with a resistor.
I'll edit my post above.

No doubt... If you install a resistor you will put another resistor in a series... Which will render the gauge useless
