All 7 1/4 rears the same?

Garrett Ellison said
10 inch drums and shoes are wider. The axle tubes are shorter on the 5 on 4-1/2 wheel bolt pattern.

So the 73 and later 7.25’s with sbp are the same as the earlier ones but 73 and later with bbp are the slightly narrower ones?

9 and 10 inch brake 7 1/4 rear ends are different width.
