Trouble installing windshield in 69 b body

My installer with 20 years experience is having mega trouble trying to get the windshield installed in the car. Almost seems like either gasket is too small or the glass is too big. Any ideas?

Seriously, get another installer, someone who's actually worked on these cars 40 years ago, most glass installers don't have a clue on installing B body gasketed, folding lock strip windshields

Actually he has done these before. I'm just questioning the crappy after market parts. I'm not sure there is any installer in this area with that experience. But I do greatly value your opinion and input. Thanks

Some 4 door windshields are different heights than the 2 doors on some cars, so run the number to double check the application.

There is a difference in heights in 69 B body 4 door and 2 door cars. The 4 door being taller.

had the same problem on my car. 2 different windshields of different brands and 2 new gaskets of different brands. no combination would work. the installer has been doing glass for bout 35 years. the lock strip kept opening on its own. finally went back to the old gasket which had been replaced in the 90's. both windshields would work with the old gasket. good luck

Maybe I should ask who makes the best after market windshield gasket.

Now I am worried, just got a new gasket for my 68 restore. Long way for glass install though.

Use the Metro gasket.

Metro gasket arrives tomorrow. I'll report back with the results.

Just had the windshield installed in my 69 Charger last year. Seems like I used a Precision gasket and new glass from PGW.

It was a real pain to install, the installer specialized in old car installs, and he was struggling. His theory is that the opening shrinks a bit when the car sits without a glass in it for years...He used glass cleaner to lube the glass to slide in the gasket.

His theory is that the opening shrinks ????? WHAT?

I kinda thought that too when I read it, maybe metal acts different up north. I'm gonna go with inferior aftermarket parts.

my glass guy uses nothing but Precision brand gaskets. He always wants the gasket removed from the package and hanging up for at least a week in advance. i just hook mine on a nail in the wall as soon as it arrives.

We also will set them out in the sun around here which I sure helps.

Now that is a new one... Sounds like some brain shrinkage from old age to me...

Went to precision gasket website, put in 69 coronet windshield gasket and it returned no results found.

While I agree it is unlikely that the opening size changed, my car sat for 20 years with no glass in it. The windshield is a part of the structure of the roof..
Anyway, that is what the guy said...
The new glass is about 1/4 thinner than the factory stuff as well.

Not in your era of cars.. The "windshield is part of the structure" thing came out later 74-75 so cars could be lightened for fuel mileage. This "structure concept" was about rollover accidents. BOGUS that a broken WS is going to add any structure to a roof.. The door glass, backglass, yes until they explode ( tempered glass)....

1/4 " thinner? there is no way.. Installed thousands myself and there is just not enough glass to start with to subtract that much from the thickness....

I think he means 25% thinner.

Received the new gasket from Metro on Friday, and it sure feels different than the other one I have. Hopefully we'll know come Monday morning.

Probably meant a 1/4 inch shorter, seems that would make it easier to install though.

Good luck, make sure to give the final resolution please.

A 4 door windshield wouldn't even come close to the gasket in a 2 door frame... it's more than a small difference.

correct 25% thinner.

My mistake.. That sounds better...

25% thinner???? Maybe that's why they don't take much pressure till they break. Now on to the third windshield since one and two have broken. Some days it just doesn't pay to get up.
