67 Dart 83/4 rear w/B Body Drums-69 Sport Satellite 11” what are the correct Brake shoes to use?

Yea- when I measure the shows from edge to edge they measure 10.5" so I'm thinking maybe the 11x2.5 shoes like 5.7 Hemi suggested as a easy starting point since I have my axles all bolted/sealed up but I do appreciate your detailed explanation and all the help.
I'll score a pair of the 11" pads and let you know what shakes out.
