'64 Barracuda trans/shift lines question?

Open out a cardboard box and put under it. Mark a line under the bellhousing, a square under the pan, and a line by the rear output shaft seal. Put a jack stand or something on it so it doesn't move. Come back in a day or so and see where on the cardboard the spots are. This will help indetermining what the problem is. Since its a 64 model, the tranny cooler lines were made by the Roman slaves and are probably brittle and seeping. May have had sections replaced with rubber hose, or who knows what. Pan gasket may be leaking. Output shaft seal, front seal, a multitude of places for a leak to occur.
