I have the two bleeder screw late rear calipers on my 75. Can I replace them with the earlier one bleeder type. Any down side to this swap? Can it be done? I just thought I could rebuild the one bleeder set while I leave the two bleeder ones on for the moment. Also inner piston on the two bleeder left side is scarred bad from some idiot that tried to pound them back in instead of using the back clearance adjuster ( not me)

Purpose wise they are the same. The internal adjuster is different on the single bleeder.
