Tire size for a 68 Dart

I think you will be about perfect with the 205/70R14 on the front and could leave the 225/70R14s on the rear. I have those exact sizes on my 68 GTS and I think it looks very close to factory. I think a 205/70 on the rear would look kind of small in diameter. I would post pictures if I knew how. If you are interested in seeing a couple pm me and I can email them to you.
