P205/75 R14 or P215/70 R14

205-70-14s are the closest dimensionally to E-70-14 stock tires. I've tried 215-70-14 on my 70 darts and you have to be really careful of the outside edge (corner) of the tread and the lower front corner of the fender opening when the wheels are turned to the critical point - sometimes you can adjust the strut that holds that corner of the fender opening. Never had that issue with 205s. I also like them because I have 245-60-14s on the back and the sidewall height is almost exactly the same as 205-70-14s on the front.
