C3 1971-Coupe Cabin leak

[Tony]

Greetings.

Before storing from last season, I noticed that water would accumulate behind both seats after a rain, car parked on apx 10 degree incline. I can't seem to find the entry point.

T-top seals and door seals are NEW. Tops were adjusted when seals were replaced. Rear window seal is good. Rear vent drain tubes new!

Any ideas? My next step is to completely strip the inside from the T-bar back from the seats to the carpet and trim, then drive under Niagra falls!!

Thank you.
Tony

I have block - off plates instead of the "astro-vent" mechanism on my '72 A/C equipped car. While chasing down what could be the same kinda leak on my car, I discovered "dime" size rust holes in these plates ... certainly was the source of my leaks ... they are located behind the vent "wells" on each size.
