Stock 1970 340 Duster front tire size

Hello everyone.
I'm looking for front tires for my '70 Duster. I have 195/65/14's right now that I don't like. They don't look right on the car. I gottem because they were FREE! Anyway, Should I get 205/70/14's or 215/70/14's? I have some really nice polished US slots on the car so don't want to go to 15 inch wheels.

Thanks!
