rear glass install

[trevor74]

SO I wanna install the rear window in my 74 charger but I went to go put the weatherstripping on it and the bottom part is way to big, by like 3 inches or maybe a bit more? Is that normal and also any tricks on getting the window in without breaking it?

The weatherstripping came with the car so I dont get why its so much bigger, it fits great around the window but the bottom is to long, could I cut it and glue it?

thanks

I haven't installed a backlite in a 3rd gen, but I was assuming it was like a 2nd gen... it doesn't have weatherstrip, I thought it was installed with butyl tape. I could be wrong though.

***EDIT*** Found a Mopar Muscle article, installing a backlite in a '71 Charger RT, should be pretty much the same, hope this helps.....

that does help somewhat, but Im a bit confused because my car came with an extra thing of weather stripping in the trunk and it seems to fit the rear window but seems a bit to big in one spot so Idk

Sounds like the weather stripping that came with the car is not the right stuff.
On my 72 Charger I used the Butyl tape that you can buy at any automotive supply store. I used the thicker stuff 3/8" since the window channel isn't perfect, also if you use the thinner tape the window might set too low and you will have a gap between the window and the trim.

On my 71 Charger that I am currently restoring I used the urethane that the modern cars use. It's supposed to have better adhesion and a longer life than the butyl tape. I have to agree on the adhesion part. My Chevy work van got T-boned and I had to replace the passenger side doors including the cargo doors. The salvage yard cargo door window was broken. I replaced it with the window from my original door. The only thing holding that window in is the urethane caulking, no clips or moulding and the window is still there.

A couple of threads on this subject.

No weather strip was used, just butyl tape, or like mentioned it can be urethane in like modern cars.

Also there are two rubber blocks that need to sit at the bottom edge of the channel. When you install the window it will want to slide down. The rubber blocks act as spacers which the window will rest against so no part of the window is actually touching the sheetmetal.

Ill take some pictures for the weatherstripping tonight hopefully

But If is use urethane wont the window sit to far down and the trim not sit right? the trim we be right on top of the window wouldnt it? I always thought it had weather stripping around it to take up some of the gap and make the window sit up higher

Maybe someone will chime in...Im not sure with urethane, but with butyl tape, it comes in different diameters. 5/16 is what you need unless your window frame is damage or distorted, in which case, you would probably wanna get 3/8.

The urethane caulking is not runny. It's fairly thick like regular caulking. I put a large bead, about 1/2" thick all the way around the window channel. The back window only weighs around 20-25 lbs. so it doesn't push the urethane out. After I laid the window in the channel I pushed (gently) all the way around the window to bed the window into the urethane.
Another tip. When you go to install the window trim snap all the trim together first, then snap it into the retainer clips.
