79 Bronco Windshield leaking
I just bought a 79 Bronco that had caulking along the top edge of the windshield seal. It leaks a little bit in the corners. A friend of mine that owns and runs Advanced Kustoms where I live told me it was probably because the cab is rotted with rust some. The seal is in good condition it is still pliable. My friend told me to pop out the strip in the seal so I could fold the edge of the seal up and fill it with caulking all the way around. This way the caulking is not visible so it looks better. My question is what is the best way to remove the strip and what is the best way to install it again?

No caulking is needed for the 78/79 Bronco windshields. Installed properly you just don't need caulk. Your friend is either correct with the rust or there is so much dried up caulk in there it is causing the leak. Best thing to do is pull the windshield, clean all of the old caulk out and if your rubber gasket is ripped or dry rotted replace it. The lock strip, if that is what you are reffering to, easily pulls out. You will need a new one when you install the windshield which is available most anywhere.
If it is a rust bucket and you don't care caulk away.
The windshield is really quite simple to replace.
With some properly placed wire the windshield gasket will roll itself into place.
I also use a small hook tool like this to help pull the gasket in place if it gives me a hard time.

Rear Top Windows
No bucket of rust by any means. It has the common rust like all Ford trucks and Broncos, but it is still decent. Thanks for the info on the windshield. I have another question that maybe you can answer. Someobody replaced the two top quarter windows with plexy-glass. I recently made a great find at a local junkyard and got two factory windows to put in it, with a extra set of seals if I need them, but the other pair still looks good. What is the best way to install these windows? The wire trick? How should the wire be placed to make it work properly? How do I get the old ones out. The windows I got from the junkyard were already removed from the vehicle. Looks like the basically push in, just have to get the lip of the seal on the inside of the top.

To remove the side windows start on the inside front top corner and slowly roll the gasket out while putting pressure on the window working your way towards the back of the Bronco. It takes a bit but it will eventually start to come out. All the time you are rolling that gasket down maintain constant pressure on the glass and it will go. When you get the top completely free the sides will be a piece of cake to get out. To install, set the glass in the gasket, place the lower edge of the gasket on the top and while pushing the glass in slightly work the gasket back over the lip of the top. Easiest way to do it is with some weed wacker string, the nylon rope type, place that all the way around the inside lip of the gasket and put your 2 ends at the bottom in the middle. While pulling from inside on the line have someone else apply constant pushing pressure from outside on the glass.
If the front windshield area is not severly rusted I'd pull the windshield and clean all of the crap out of there and reinstall using no caulk.
Oh and all Ford trucks don't have rust. My Bronco came out of Ca and was rust free.

I installed my new back windows today, I couldnt believe how easy it was. It looks so much better with the original glass than the black painted plexy glass the previous owner put in it. Fits much much tighter now, so I wont have to worry about leaks. I didnt have enough weed eater string left to use so I just rolled it over with my fingers, they are a tad bit sore after all that lol.
About the rust and yours being from CA. Mine came from Kentucky, just a few miles from where I live. There are not many Broncos in this area and the ones that are here have been drove hard and put up wet so most of them are pretty much rusted away. I just got lucky to find the one I did before it got bad.

i had a professional shop install my windshield- they cleaned all of the metal with some kind of alcohol, applied some black permanant sealer to the flange all of the way around (3 coats) then installed the windshield, as i remember, the origional windshield had sealer applied in addition to the rubber gasket. no way its gonna leak!

I've pulled and replaced probably 4 of these windshileds and have never seen a sealer used. There is a felt pad that is glued to the metal edge of the cab but no sealer. I have never used a sealer or caulk and all so far have never leaked. I'm not a professional window installer either so that might be why.
