!971 Fury leaks water

My 1971 furys leak water onto the front floor pans and I don't know where the water is coming from. I had a new windshield put in and made sure it was sealed but it still leaks. Do these things have common leaking problems, if so, where does the water usually enter at?
Thanks.

wiper pivoit seals.
Heater box drain could be plugged
drains for the cowl could be plugged.

for a rocket scientist you should know that water comes from the sky, i suggest getting a datsun:grinno:
