If that converter works, you won't need to isolate anything. The Model A ignition system is what it is and generates lots of interference. The CB radio operates on AM (amplitude modulation) so it's prone to a lot of interference as a result. It's like the AM radio in your car is subject to interference (static crashes) during a thunderstorm.
Get a CB radio with ANL (automatic noise limiter) and/or a NB (noise blanker). Both features are better than a radio without them but won't
cure the static issue.
This is why Edwin Howard Armstrong invented FM radio...but that's another story.
I'd test that converter before installing it in your car.
