Just last fall I put 205/70R14 Uniroyal Tiger Paw white sidewalls on my '68 standard. They are pretty decent tires for the money. I tried to get a set of Firestone white sidewalls in the same size, but they don't make them any longer.
I wish Michelin still made whitewalls...I replaced a 15-year old set just because the rubber compound had gotten hard, which made the car ride roughly and bounce a bit over bumps. I have Michelins on all of my other cars and they are the BEST!
And, lastly, cj750 states, as long as your front end is aligned properly, you will definitely enjoy the ride.
