I had to cut the line to take down the plenum. I used an irrigation coupler to reattach it. There is another one on the other side. So 2 drains 1 on each side. The line runs inside the rear pillar and exits underneath. Blocking the rear outlets helps somewhat. But seriously, this was good in 1969! Almost 50 year old technology......... I love old cars and trucks. If you what to be a purist and drive one every once and awhile fine. If you're like me and what to drive one and use it, up grade where you can. AC is one area that you can.
