Widest width Tire, Front/Rear on '65 Dart

Anyone know what is the widest tire I can safely go without rubbing on the front/rear of my Dart?

I was thinking 235-60 14's on Front and 245-60 15's on rear. Any idea if this will work?
I am running a 245/14 in a 7" old style slot wheel , not sure of the BS, no problems.
