I'm not sure if you got your question answered as I believe you wanted to replace the rear shoes. Take a set of the rear shoes to the local Auto Zone guy - he can match up with his books. Also take a set of the old rear brake springs, clips and emergency brake rod to get new as they most likely were never replaced. Hope this helps.
