{Chrysler 300} temp senders / gas tank senders - ohms

[John Grady <jkg@xxxxxxxxxxxxxxxxx>]

Anyone have any idea of normal min max of the various senders ? I know gas tank from 60-62 something  like 10 ohms full 80-90 empty , the correct thermal style gauge temp senders must be same — as thermal gauges are identical in dash 60-62 , but gauges used in 57-58 ( and ? 59 ) are differential wound coils in the gauge , so no regulator needed , but senders for those might be higher ohms ,
I have a lot of mopar temp senders can’t tell if same or not across those years . 
Ford senders look the same but usually larger thread 1/2 and higher ohms too ( 400 cold , ) mopar seem about 150 at room temp 100 in hot tap water . 

This is all related to aftermarket gas tank senders seem to never be right .... would like to get to bottom of this so not having all the fun of gas tank in and out , or run out reading 1/4 , ,,, or reads empty but takes only 12 gallons etc etc . Or temp gauge never comes up enough in 57- 59 . 
Input obviously  welcome on any of this
