SBP 10" rear brake drums and shoes

I recently put an 8 3/4" rear into my '68 Dart. Casting #2881489. The rear came out of another A Body but I don't know model or year. I am having a hard time finding replacement drums and shoes because parts stores can only apparently search by year, make and model. The drums that came off the 8 3/4 have a few markings: Max. Dia. 10.090" and 35789. I assume it's a casting #. It also has the Chrysler Pentastar and 550. Drum inside width is 2" or 2 1/4", not sure. Does anyone know what A Bodies came with this set up so I can have the parts store search that way and start somewhere? As far as the correct linings, I will probably have the same problem finding a match. HELP!
