Delco Freedom Maint Free C89 Battery wanted
 

I am looking for a C89 Delco X better known as the Delco Freedom battery. My 1973 SD455 was ordered with this $26 option instead of the traditional R89 battery. Can be dead, useable or NOS. They look like this, although this has the later "DELCO FREEDOM II" decals instead of the earlier "DELCO FREEDOM" ones:
