Front hanger spacers

Is a 66 B car that much different than a 65? Ran the same size rear tires on my 66 with no issues mounted on 7" cop car wheels. Well, the only issue was when pulling into a steep driveway at an angle and the tops of the tires would rub the inner fender wells a bit but that was it....
dunno, the rear wells look similar but the A has that rocker trim. I think thats the interference point. Have to get back under there on the non mounted side and look again.
