Then, since they are readily available, either Cragar S/S or Wheel Vintiques in 15 x 6 with around 4" backspacing (or 7" with 4.5" bakspacing). 215/65-15 tires will fit on the front, so if you want all 4 the same size, that's the best size. Maybe, if you're lucky, you can get 225/60-15 on the front, but it's "iffy".
