EVERY American automobile and light truck before 1952 was 6v. Packard was positive ground through their first 12v models around '55, then flipped to negative. As far a operation, it isn't going to care if it powered positive or negative ground.
Of course there is always the possibility the car has been converted to 12v. Meaning radio may be modified as well.
