Brian,
The best rear heater core info is at http://www.benplace.com/rear_heater.htm

To disconnect the hoses, just have a couple of wine corks ready, unclamp
  the hoses, pull off and cork 'em. It helps if you have unbolted the
heater first so you can tip it up. Keep a rag handy anyway cause you
will lose a little fluid.

Good luck with it!
