Where is the drain for the condensate drain on a 66 Skylark? I get no dripping while the car is running, but after it sits for a while, it makes a large puddle. I think the drain may be plugged, but for the life of me I can't find it. Looked on the firewall, took a mirror and looked behind the engine and can't seem to find it. The manual makes no reference to where it is located. TIA
