There are two hoses that exit the heater core directly behind the engine, towards the left. They are secured to the heater core with conventional clamps & extend to the drivers side of the car where they connect to steel tubes that terminate in the engine with slip fit O rings and a support bracket. One of the hoses connects to it's steel tube with a conventional clamp & the other with a "special" fitting that is part of the hose. The hoses have preformed bends in them to wrap around the back of the engine.
They are very difficult to replace. I removed the air intake "horn" to gain access to the heater core ends & removed the distributor to access & remove the steel tubing from the engine. Mine were leaking at the O rings as well as at the tubing to hose connection.
