holy back windshields batman!

[keith2084]

1971 dodge charger...the guy I Baught the car from had the back glass out repairing some rust issues around the bottom corners. Has anyone had any experience putting in a back windshield on this particular car. I need to know what I will need to put the window back in the car. The glass is a little hazed over and dirty. If anyone has any tips or tricks and a list of products I can use to clear the glass up. I would greatly appreciate it.

The hazing is the seperating of the 2 sheets of glass and will continue to get worse. I would look for a better windshield or get a new one.

Install is easy clean your glass up around the edge put the uv protection on (some kind of paint , then install you double sided sticky rubber seal and install there is extra space so you need to make a shim and stick under the window so it is even I think it's like a 1/4" but could be less . I had an extra glass I just gave it with my rt there not easy to get nor cheap last time I tried to buy a new one it was $1000+ shipping I went and bought a parts car to get one instead. So when ever I find any in decent shape I buy them even if I don't need them but I try and help other mopar guys so I always sell them to people in need I will double check there could be a spair in the rafters I'll need to count how many is in my rack

Actually, a windshield, or windscreen, is only on the front of a car. The back glass is called a backlight.

I've only installed one, and it was installed by running a bead of silicone adhesive around the opening and applying the glass and then the trim. I don't think they use the same rubber seal as windshields do.

Thanks guys. I'm gonna clean the glass. See if that helps. It came with a seal kit. So wish me luck.:hello2:

The last thing you want with older vehicle wndshields and backlights is to mount them in a permanent nature - that is epoxy or adhesive in the rubber's channel. Unlike modern cars, the front and rear glass is not part of the body structure and are not suppose to add integrated rigidity for the body and air bag deployment. These older, larger cars have a tendency to flex and twist so if the glass were rigid to the body it may well crack under stress or cause separation prematurely as the frame twists on bumps and potholes. This is most evident when you jack a car and can't open the doors. If installed in a rubber window gasket properly you should never need any sealant unless the mating surface ( body side) is rusted, deformed or uneven. Even then, the sealant only goes between the rubber and body and the glass is left to float in the inner channel of the rubber. It's almost impossible for water to go down in the channel on the outside, under the glass and back up the channel on the inside. If you don't use a rubber seal it is best to use a highly flexible adhesive like butyl rubber tape or in a tube which you should really ask a glass installer for.

Didn't they use that "butyl tape" for the front and rear? I think 3M makes it. Thought I read 3/8" for the front and 5/16" for the rear. Just kinda confused now because I'll be doing the same on a 71 RR soon. Either way, I just want it to be correct and seal both.

I did original butyl tape on the rear window of my 73. Best way to do it was to put the tape on around the opening, then using suction cups on the glass I installed the window from the inside of the car because I could get better leverage from inside by turning it sideways passing it through then placing it. Easier to do unless you have two people. Keep in mind, once it sticks your pretty much done.

Use 5/16" butyl tape and there needs to be a couple rubber spacers at the bottom.
