77 windshield leaks
« on: September 24, 2011, 12:29:14 AM »
my windshield started to leak lately only when it rains hard, iv heard somewhere but dont remember that the 78 and newer had the urithane seal and the older ones didnt, so does that mean the windsheild is clamped in or somthing with a gasket, i dont want to take it apart and find out through trial and error

June of 78 they changed to urethane "glued in" windshields. The glass is bigger than the traditional sized glass and they don't use a gasket that wraps around the windshield pinch weld.

Easy way to tell is to see if you have a vinyl "molding" around the inside of the windshield. From what I have seen it is matched to the interior color. It has a rough pattern to it, and can be pulled away from around the windshiled. If it is a smoother black rubber it is a gasket type windshield.

Anyone who has installed a gasket style Mustang windshield will know the key spots to seal up on a gasket Pinto windshield (the corners). So if you don't want to seal it up yourself, look around for a reputable glass installer who does old cars.

 Mine3 leaks some too, its a 78 wagon,and it has red interior but black around the inside of the windshield.I guess its an earlier 78. The black part on the inside has a split in it,and I just put some silicone in it from inside and havent seen any sign its still leaking in so far at least.

Your car has a gasket. Steele Rubber has them for about $100.00 plus shipping. You will need a small 1/8" wide PVC tape to seal the window flanges  or use black sealant and then put the window in the gasket etc.. BTW if your car has mouldings in the window you will need the clips to hold it in place.

Where does one find the PVC tape? The PVC tape applies to the metal flanges FIRST prior to the gasket, yes?

Is that 1/8" wide? How thick is it? Thanks.

it's 1/8" thick tape that is applied around the inside and outside of the windshield's window frame pinch weld. It helps to seal between the body and the gasket.

For my 78 and 73 I have a urethane seal around the gasket. A company here called Speedy Glass sold me two tubes of their black urethane sealant for $18. It has to be heated (I stuck it in the oven for 45 minutes on warm) before use, as it is extremely thick. You have to work fast with it before it cools or you will have sore hands from using the caulking gun so much. An electric caulking gun would make it cake though.

1) Don't be surprised if you don't get it sealed up the first time, I had my 78 Sedan done by a reputable glass shop with a lifetime warranty on leaking installs and had to take it back three times to stop all the drips.

On my 73 Station wagon I did it myself and it leaks a little bit at the top of the passenger side pillar and above my left leg on the top. I just need to get back in there and pump some more sealant in.

2) The corners are the weak spots of the gaskets, new old stock or re-pop. Be sure these get extra sealant!

3) don't install the bright work until you are sure the leaks are all fixed or you will really begin to hate the bent molding from removing them over and over.

4) The molding clips should be in decent shape, I reused all of mine and the molding stays on just fine. If you absolutely need some due to some bending or breaking you can get them here:

5) be gentle with the original windshield. With time they become brittle and easier to crack.

6) To remove the old glass, just cut away the outside of the trim that folds over the glass. The windshield can be pushed out from the top, inside and will come out with ease. It will be stuck a little bit, but it shouldn't require the BFH (big f-ing hammer) to remove, just a slight amount of pressure and it should pop free.

7) Before finishing the glass install, you will want to pump some sealant on the outside lip of the gasket, between the gasket and the glass.


I did a partial photo log on my 73's windshield install, which begins here:

Almost forgot! Use some 550 para cord during the install. Start at one of the bottom corners leaving about 2 feet of excess and four inches away from the end of the windshield. Wrap it around the gasket on the glass, in the body groove of the gasket, overlapping on the bottom to the other end of the windshield, again up to about 4 inches away, and a two or more foot excess.

Position the glass at the bottom first, then lay it against the the car. With an assistant, have them push the glass down and in, lightly, at the top to help keep the windshield seated. With the pressure applied, pull the 550 cord that overlapped, out. The windshield will begin to seat. Once you reach the corner of the windshield frame, pull the other cord along the bottom out. The windshield will now be seated along the bottom!

You will need a 90 degree pick tool like I used (it's what the glass installer used on my 78), to help pull the inside lip of the gasket around the window frame pinch weld so the gasket doesn't tear.

Use glass cleaner as a lubricant on the gasket and the frame. It helps a lot to pull the gasket in around the window frame pinch weld without it binding and tearing.

Any other questions feel free to ask!
