Unless something has been modified to use a solid state replacement component, nothing in the car is polarity sensitive except the radio and even that depends more on internal polarity after the vibrator, transformer and rectifier tubes so depending on how those are isolated, it may even work.

The spark will be a little less efficient with the coil backward and the generator only needs a quick polarizing to work properly and time would probably take care of that. If you had an ammeter, that would have read backwards but still worked. Gauges are all bimetallic, so just rely on a coil heating up.
