Windshield gasket replacment

Hi all and thanks for the info
the car did have a vinyl roof, no longer and the holes are filled.
I did check under the dash with water running over the glass, the
gromets for the wipers were leaking, fixed that problem
Will not hurt to double check were the leak is coming from, I'll remove the
kick panels and run some water over the car. At one time when it rained I was
getting a clove box filled with water, which I still can't understand, since it laps
over and it sits back from the front edge of the glass and there is no metal that
would allow water to run near it...
I would think the only safe way of removing the glass is to cut it out.
Its possible to cut behind it, if you have a long enough sharp edge
but getting those A pillar covers out is not easy.
Also I will probably go ahead and replace the vinyl dash cover, it's
pretty bad now.
thanks again
Best
