86 CGT A/C Evaporator Drain leak???

[s4qtro at bellsouth.net]

after a trip from Orlando to Jacksonville and back, i noticed a moderate amount of water in the passenger floorboard (actually my girlfriend did whineing that her feet were wet) of my 86 CGT.  When I checked the rear passenger floorboard the water was about an inch deep.

It was also raining on the way up, but i have noticed that there is still a drip when the sun is shining away and the A/C is on.  Dad said that the Evaporator drain hose might be plugged, but we couldn't find it to unclog.  anyone know exactly where it is or what color it "should be"

thanks,
