New Auto Meter Gauge/Sending issues

You guys might want to sit down with some test resistors and justify how the Autometer gauge compares with the original "specs" The Mopar gauges were supposed to test as this:

L = 73.7 Ohms (empty)
M = 23.0 Ohms (1/2)
H = 10.2 Ohms (full)

Maybe the Autometer gauge is nowhere as "matched" to the original scale as it might be
