Yes, pretty sure 10 ohms full is about right ---and accuracy of full really does not matter much, sometimes gauge goes over full , does not matter, but E is critical , 60 ohm E seems too low in ohms to me , but he might have measured that on a tank where float is not moving its full range..fix by bending arm if needed. Float must go to the bottom of the tank obviously. . I see personally 80-90 , aftermarket gauge dealers say mopar is 90 E , 10 F and one fellow responded to me on a later Chrysler his is 100 E. so 90-100 ; lower ohms it will not go to E but will stop dropping just above E
The cold ohms of the temp sensor are not important ,except what it does predict about what it will be hot, as the needle will just stay at C longer if cold ohms are somewhat high..they seem to be 150 ohms at room temp about 100 at 130F Tap hot water temp ,--- so same gauge needle place at 130 F as E position on gas tank, (as engine passes 130 warming up), but soon getting into middle. Following that thinking , it must be like 10 or 20 ohms at 212 degrees , these values are for senders listed as correct for 1960, in mopar bags..
However if you use this sender in a 57-59 , it goes all the way to H end at 185 , looks like the engine is too hot. I have seen this twice so I know that is correct. On mine I added a 30 ohm 2 watt resistor (mouser) to the sender lead in series with the sender, at the sender , which put it dead center when at ~ 185 degrees in the engine , so all this info ought to let you fixe temp sender, so gauge is in middle with engine at right temp .
Gas tank more involved as there is some kind of curve built into the winding wire (it changes width of winding if you look at it , so not only E and F values but how that tracks. Bottom line ,save the old one. Do not increase tension on the rubbing arm, I did that (yeah!--make it better!) it rips up the resistance winding in a few weeks, leave it alone and just clean it , float down about 90 ohms float up 10 , don't worry about 10. For thermal gauges (1960 up) . Don't know about 57-59 or before 57, but someone might have one out of the car as part of resto. Measure ohms, arm up, arm down?
We will get there!
