Duster with b body 8 3/4 wheel set up

I don’t know. Didn’t measure before hand. I was told it makes it a little wider. Rear hat to hat is 60’’ Front is 58 3/4 now. My b body rear was 54 1/4 flange to flange. Wish I would’ve gone 1’’ taller in the rear, like a 255/50/17 but a lot more options with the 255/45/17s.
