Correct. All BBP backing plates will interchange with any of the BBP axles, doesn't matter if the housing is 7.25, 8.25, 8 3/4 or Dana 60. The axle flange offset was the same for all of them.
What you can't do is mix and match SBP and BBP backing plates. The plates have a different offset from the end of the housing to make up for the axle flange stand off difference.
