John, On my 84 the center console under the center of the dash pulls straight out and off.. Then you will see two hoses that have formed curves going from the heater down through a rubber seal to the area behind the radiator that you get to by lowering the spare tire. One goes to a valve and the other has a metal coupling. From the valve and coupling back to the t's going to the rear heater it's 5/8" heater hose. On the return line to the engine it's also 5/8" however the supply from the left cylinder head to the t it's a special molded hose with one end bigger and the small end being 5/8". For that you can get the same hose from a 85-92 golf/jetta for about $9 that has different formed curves but has the correct size ends and works fine for me. I got 2 new plastic replacement t's from vw that require special hoses. I was able to get only 1 hose to rear heater and for the second I'm going to find a plastic maybe nylon t that will work for 5/8" hose and save the cost of another $29 with shipping 18" hose!
