Simple test. Unplug the sending unit. If the reading drops the gauge is good. More than likely it's the sending unit. The higher the resistance the lower the gauge reads and vise a versa. There is a possibility of the gauge wire shorted to ground somewhere.
Check to see what the resistance is...

Do have a 3488764 three speed switch. In the off position on the switch, test the impedance between the B and P terminals. That should read 0 Ohms. The second test is between F1 and the metal frame of the switch. That too should read 0 Ohms. If both of those tests read correctly, then test the...
Some S codes. Maybe the wrong key was hit.

The motor and trans also have a partial number on them. You might find a build sheet somewhere or an old registration. Or a licenses plate form the car.
With that gear ratio, I want to say it was a slant 6 engine or a 318 2 barrel. So what motor mount are there.
The 2.76 gear ratio was typically paired with the TorqueFlite 3-speed automatic transmission (A833) on Dodge Challenger models around 1970-1973. According to factory specifications, the...
