will a 235/65-14 fit the front of a 70 dart ? it is 26.0" tall
or would 245/60-14 be a better fit ? it is 25.6" tall

Jerry,give me a call at home and i will get you some 15 inch wheels built with small bolt pattern centers,or I can cut out your centers and weld on some 15 inch wheels to the ralley rims you have,mrmopartech
Would you want to install 15 inch on all wheels?

Is there an advantage to 15" wheels ? I have a spare set of rally wheels that I guess I could use , just not sure I want to screw with them . Also have a set of 14"Ansen sprints I don't know what to do with , think they need a spacer/adaptor to fit the Dart .

I think this one is even a little better.

you can put wheel backspacing or offset or different widths and it give a good idea of how it will look.
