73 Dart tire size question

I just went out and took a tape to my 70 Dart. Same wheel wells as yours. Look like it is going to be very close with a 28. The fender lip sticks out another 2 inch from the wheel well so if the tire sits in far enough in the well it will miss it and have room. If the rim does not have enough BS on it the lip looks like it will be in the way and wll need cut or there is enough room to move the rear back about 1 inch. You can do that buy putting a 1 inch block behind the front hanger.
