Need a profile pic of your car

I'd put 225/70/14 on back and 205 or 215/70/14 on front.
68 Barracuda has big wheelwells.

I have manual steering on my b-body with 225/70-14 on front, not a problem steering the car. My wife drives if also.
Yes it's a wimpy tire but was close to stock. Going on 68 Barracuda.
