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

Sorry for not being clear when I say they are not working.
When test fitted- the shoes seem to be too long. They do not fit inside the drum length-wise.
Width-wise- they are fine( they are 2.5" shoes).
5.7 Hemi- thanks- will give it a shot and 72 bluNblu- WOW- thanks for the detailed description. I really appreciate the details on how to measure the backing plate. I'll get that done and get back with you- just gotta pull the axles back out(boooo) ;-)
