The car body definitely looks like a pre-1980's. Looks like a narrow B-pillar and the car was at one point 6-volt. The floor dimmer switch is another indicator of pre-1980. Check your vin plate and see if it has an "E" stamped after the vin number. This would indicate a factory refurb. The dash is from the later model so it could just have been changed out by someone or it could be the factory refurb.
