Depends entirely on what the backspacing of the wheel is and what you did with the spring perch’s on that B body 8 3/4.
If you look at Lelo Darts post above he needed a 5.25” backspace on a 15x7” to center up the wheel using ‘65 B rear in a ‘72 Dart. Your specs would have to be similar since the rear axle is the same width and you’re dealing with the same body style, it’ll just be down to body tolerances and the spring perch location.
