using the multimeter set to 200 ohms, and key on, it reads -172 from + coil to grd
using the multimeter set to 20k ohms, and key on, it reads 8.5 from plug wire hole to grd.
Not sure if any of this makes sense. Does this confirm it might be the coil? thanks for any and all suggestions.

For the moment, forget anything about reading ohms.
All that matters, whether with the test light or the meter, is that you see 12V at the pos side of the coil with the key in the run and start position. That is good.
Next, As I tried to explain earlier, what you should see on the negatives side of the coil depends on whether the points are open or closed at that particular time. So, with the key on, measure (or test light) the negative side of the coil and turn the engine by hand far enough that you can see the points open and close and tell us what you measure (or the light does) as they open and close and let us know.
