Check here. You can reach it in the car without removing the windshield. Not easy but can be done by someone with little arms and Belly.

Thanks Steve. I learned something new today! 
Deffinetly something to watch when removing glass .nice video!
Appreciate the video, but that hole area you are referring is in no way connected to the square hole cowl drain. Thats a completely separate piece spot welded on. packing it with dum dum does absolutely nothing for a leak.

Most of times glass shops fill drain holes with sealant which can prevent draining.

I need an explanation. Does the leaking really stop with dum dum pressed into the little bracket at the end of the straw shown in the video? Assuming no rust out in the trough. I've got a 67 Barracuda that leaks in the front windshield mainly on drivers side. Car has good rubberstrip. What does anyone say?

Let the boy go !
I was told to use this for leaking windshield gaskets. Doesn't harden. Put it in the gasket grooves before installing. Gets messy so have rags and wax and grease remover. Still haven't done it but did buy it.

Same for me.
This has been my observation as well......I will have to take a closer look before the windshield goes in.

that's not factory
Looks like the video in the OP (original post) is no longer available. Any chance that you have a link to the new video? Subscribed and thanks!
The square holes at corners are drains. They lead to the cowl. On many cars they are plugged with seam sealer from new.
I have a body here on a rotisserie right now with one that is plugged.
Across the bottom of the windshield there is no channel like the sides and just sits on 4 tabs . The lower rubber sits on these tabs and any water that gets in that trough runs to the corner. If it gets under the sealer and the hole at the corner is plugged with seam sealer ( and many are) the water comes up over and drips on the dash . On the drivers side it goes directly on the fuse box and headlight switch.
When the upper cowl was attached to the lower cowl at the manufacture they put sealer between the 2 to prevent water from blowing in due to cowl vent air. Many time the excess was not cleaned out of the drain at the corners and the water rises over the top. This is what happened to the cars that the floors rotted out of on many I have seen that came here for floor rust.
So the bottom line is don't over seal the corners and make sure your car has open drains to the cowl.
One other area is the cowl dams. The sealer gets old or debris sits there and the cowl rots through. Always take the heater out and the vent box and look up around the outside. You can reseal it from the inside. Do it careful I cut my finger on one pretty deep and sealed the cut with seam sealer before I noticed.
I'll get another video when we put the new windshield in the barracuda. Todd didn't listen and his leaks like the Niagara falls.
You can put holes in the side of the cowl with the fenders of and use a wand to spray Chassis saver in to stop the rust. There is no paint in there and they are all rusted some worse then others. I would suggest doing that before sealing it. The bad cars just take the cowl off and fix it right.

Went to the garage and snapped pictures of the open holes in 2 cars and one that is still plugged with seam sealer. Arrow shows the way the water flows in
and you are sure it isn't the wiper seals that have eventually leaked on the drivers right foot on every A-body I have owned... just askin'
Yes the wiper pivots do leak with age. But even when these cars were only a couple years old they were leaking. That is why some of them are rusted so bad. It just flows in if that hole is plugged. It acts like a water spout.
The wiper seals will drip slow around the shaft when it pours or when driving with the wipers on. If these holes are plugged and usually are. They leak with the lightest rain. Run water on your windshield without getting it on the wiper shaft to check.
Don't forget The cowls rusted inside on all of them due to lack of being painted under the cowl. Some rusted through on cars that were not covered and sitting outside in the rain.
So there is 3 places they leak
Wiper seals ,
Rust holes in the lower cowl,
Blocked drains in the corner. Cars that have rusted floors have been leaking since made. Usually due to the drains plugged with seam sealer from when the car was sold new. Wiper seals will drip. Clogged drains and you'll get a puddle.
