The leak was coming from above the tailpipe where two hoses quick-connect to what I assume to be the rear heater core located in the rear quarter panel. Question 1-Do those quick connectors have rubber seals that might have gone bad? Question 2-Or do you think it is the heater core gone bad? If it is the heater core, any advice on replacing it or is it a straight forward repair? Thanks!

THESE hose connectors do leak, usually when improper tools used to remove from the heater core. remove these hoses and then with 10psi of air pressure leak test the heater core for holding pressure .
If no leaks replace these hoses or remove the quick disconnects and use hose clamps.
