How many ohms for blower motor resistor?

My original looks good (in the sense that neither side is an open circuit or blown), but I can't find a spec for what it should measure at (1970 AC truck).

I don't want to put in a Chinese replacement if my 40 year old GM unit is still good, but I'm a long way from powering it up and testing it empirically.

Anyhow, from the base to one port I get 0.6 ohms
From the base to the other I get 1.5 ohms

Those are really low numbers, I actually get different numbers on different meters and they swing around a bit. Maybe low battery in a meter?

Anyway, if someone knows that numbers should be, please let (me) us know.
