63-66 Dart. How wide of a tire on the back?

I love to see more of that 66 rear end/tire combo......it's that a 8.75 rear? Did you cut it? Iam guessin you r using mini tubs for that 275 tire...thanks
Stock wheel wells no cutting at all, 15"x8" rim with 4 7/8" b/s, i didn't like the look of the rallies
so i sold them and went steel rims, I got about 1 1/2" space between the wheel lip and tire and about 1" to the spring.And yes it's a Abody 83/4.
