Continued leakage into the cabin, have used "search"

but cannot figure out....
I know the water is not coming in from under the hood / hinge area. 2 days ago I used a coat hanger, stretched straight, to clean both the front sunroof drains.
Yet, after sitting outside last night in the rain I had water running down (weird, I know) the underdash and collecting on the floor, right next to the door sill. On both sides!
After I got motoring it started to stream down the A pillar, seemingly coming from between the headliner and the plastic pillar piece.
Is it possible that the drains are rusted? Were they plastic or metal on 123's? If rusted out, can I use some plastic tubing or something in there?
I just got done taking care of the rust in the floorboards and I'm really protective of them (ok, perhaps a little obsessive too).
I know much has been written on this topic but I feel as if I've tried every remedy previously posted.
any help would be much appreciated!
