Brake Hub help please! Sbp to bbp

Something just dawned on me tonight...

EDIT: Scratch that. B-bodies used Bendix 4-piston calipers, not the Kelsey-Hayes design.

EDIT #2: Something else dawned on me: The Kelsey-Hayes calipers and the SSBCs appear to be the same exact thing. If you can get your hands on the SSBC backing plates ONLY, you should be able to pair a set of drum spindles with the SSBC backing plates and your existing calipers.
