Never done this before so I'd rather be safe than sorry....
Thanks again for your kind assistance....
Yes, they head to the firewall. They are much smaller than the radiator hoses.
I don't know if Prestone still makes them, but they used to have a flush kit for the entire cooling system, you installed on the top heater hose. Just hook your garden hose up to it, worked great. Still have to change the t-stat and get all that old stuff out.
