66 Valiant ~ Wheel size / offset question

Good questions. Rotating would be great, and I dont want to modify any body metal at all. My budget is pretty open for wheels, and Im not stuck on one style or another. Wheels have always made the car to me.
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".
