63 Dart ignition issue

I found an MSD one that is .8 ohms. Is that closer to factory spec? Don't mind paying more if it's a quality part.

I'm not sure, honestly. There are two ways to measure and I'm not sure which is correct. The ballast itself and by the coil. I looked in my 64 Factory service manual and while it talks about the ballast resistor, it lists no specification.
