Help with 64 dart gt tire size

I just picked up a set of 71 scamp 14 inch dog dish rims and would like to place them on my car instead of the stock 13 inch rims. These rims presently have 225 70 14 on them and are way too wide to clear the quarter panel wells. Has anyone had success with a 14 inch tire on a 1964 Dodge Dart GT without modifications? I am thinking that a 185 60 14 may fit. I am open to ideas, please help.
