While I'm sure you are correct that the sources say that, I have never seen a 1967-1976 B-body with anything other than 5 on 5 bolt pattern. The application listing in many cases lists the wagon version as the 4.75 on 5, which I know should be wrong having owned a half dozen over the years. I did this conversion myself 15 years ago and back then the 4.75 on 5 was NOT listed as a viable source by any of the old books or computers. The bearing sizes between the two are not interchangeable to fit the smaller bolt pattern rotor on the spindle of a big car (I tried both a '70-81 F-body and a '71 A-body).
In 1977+ I know the 4.75" on 5 bolt pattern was the standard and only heavy duty suspension cars got 5" on 5, making finding brakes for them an exercise in fun.
