    *Car '67 valiant signet converting to 68 and up seal/trim n clips.
    I just put down some new paint on the frame. I bought a '68 n up seal and clips/screws and have a few sets of trim.
    I'm asking for any advice on the install.
    I have butyl tape and permatex window sealer. I was thinking I would put the thin butyl tape across the center and then use the sealer or butyl in the seal to pinch weld groove installing the gasket 1st and then stab the windshield into it lower 1st and then use a plastic putty knife to work the seal around the glass from the center n out to both sides top and bottom. I've seen the rope trick...and the knife trick.
    What's your method?
    Any measurement for the clip screw holes?

    Any glass i have installed i used the rope trick.

    Put window seal on the glass. Use whatever sealer you prefer in the grove that the glass goes into.

    Take a thin cord (like clothes line or smaller)and put it in the grove of the seal that will go over the body pinch weld seam.

    Put the glass in over the lower pinch weld seam. Have someone put pressure on the glass from the outside, not a lot, just enough for the seal to stay in contact with the body. Pull the cord into the car, preferably from bothsides at the same time.

    If you lined everything up correctly the rope will pull the inside of the seal into the car over the body pinch weld and the glass will be centered.

    DO NOT SLAP THE GLASS there is no need to do that and you stand a better than average chance of breaking the glass.

    If you need to add sealer to the seal and body pinch weld you can add that after from the outside.

    I am no expert but that is how i have installed glass.

      Put the gasket where it will get nice and warm before beginning work. Under the portable shop lamps works great.

        Does this type gasket have a lock strip?

          No.

          The 1967 cars have the bed lock/lock strip.
          I know I've seen the one dusters have that goes around the top and down the sides..is that what you're referring to?

          Naw. On the early cars like my 64, the gasket has a wide slot in the center that the lock strip installs in and locks the windshield in place. There are two distinct pieces. The gasket and the lock strip.

            That's the 67 style , I'm leaving that style for the 68 version with trim peices.

              Then how "I" install it is as follows.

              Put the gasket on the windshield first. Next, get a length of rope about twice the length of the circumference of the outside of the windshield gasket. You want extra rope to make sure you have plenty to grab hold of.

              Next, put the rope in the gasket groove where the pinch weld goes. I start the rope "somewhere" on the bottom side. Get the rope in all the way around in the groove good. Now, both ends of the rope will be stickin out of the bottom if the gasket.

              Next, get some Dawn dish washin detergent and lube the rope and the gasket liberally all the way around the rope in the groove.

              Then, put the windshield in, bottom edge first with the rope in the INSIDE of the car laid over the dash and get it as much of that bottom pinch weld in the groove with the rope that you can.

              Finally, with person number 2 on the outside, pull one end of the rope out to as close to a 90 degree angle to the windshield as possible. This pulls the lip around the pinch weld and installs the gasket with the windshield in it. Pull it slowly, so it doesn't tear the gasket, with person number 2 pushing against the GASKET right where you are pulling the rope out, following you along as you pull the rope out and pull the inside lip over the pinch weld. As mentioned, there's no need to "smack" the gasket as that risks cracking the windshield. Firm steady pressure following you as you pull the rope is all it takes....that and a liberal amount of detergent to assure the lip doesn't tear. Once you pull the rope all the way around, that's it, it's in. You might have to help work the lip over the pinch weld hear and there, but for the most part if you go slow and pull the rope like I described, it'll go right in.

              Finally of course is the cleanup. Let it dry really good for several days after you rinse it off and then you can put sealer on it by sticking the tip of the tube under the outside of the gasket all the way around between the gasket and pinch weld. But nine times outta ten if the pinch weld is clean you won't need sealer. I always do it anyway just for good measure.

                @RustyRatRod Check this vid...fast forward to 5 min mark.

                The gasket has grooves for the little locating tab in frame.

                That's how I install the lock strip style. The rope works much better on the one piece for me. I use rope that's 1/4" in diameter though and not "string". Do it how you feel comfortable. The last thing you want is a cracked windshield. That method above works very well for the lock strip style. Admittedly, I've never tried in on the one piece. I've just always gone straight to the rope. Probably done over a hundred and never had a problem. Does require some cleanup though.

                  Dawn regular dish washing liquid a lot of it. I use wooden paint stirs sanded to a wedge and rounded corners. Dawn will also act as a sealer.

                  Another trick with Dawn regular. When running hoosier slicks or any race tires tubeless. Always coat the inside of the tire with Dawn regular. Seals the tires and won't seep air. Tubes add to the reciprocating weight. Use it on front runners also. We always did our sprint car tires too. Works great.

                  Sucks when your tires go flat in the trailer. You'll never have to deal with that again. Holds pressure between rounds when waiting in line.

                    On the video, on the rear (or front) the thing i would do different is to work bothsides at the same time, or at least a little on the left and then a little on the right etc.

                    That will help keep the glass from shifting to one side

                      I'm with ya, thank you brother man.
                      I just really dont wanna have abort halfway through and start over.lol
                      I've seen the lock strip type and yeah you put the gasket around the window and all that and then you snap the last trip in and then you go and start it at the bottom and pull the string around up to the top I saw that video of the Ford pickup truck and they did it that way, like you're saying.

                      I really prefer the lock strip gasket though. Me and Kitty can have a windshield swapped out in Vixen in less than 15 minutes. The lock strip makes it dead simple. The one piece ain't far behind, though. Biggest thing is pull the rope at a 90* angle to the windshield and go slow. Don't rush it. You'll see what you're doing as you're doing it and you'll start to understand how and which way you need to pull.

                        All of the above is great info. The one thing I'd like to add is never ever use a screw driver to try make the glass fit into the gasket. It will break 99.9 percent of the time. The wooden paint sticks like OMM said is great, or the right tool is made of plastic and sold on Amazon.

                        I've put in over a 1000 windshields in locomotives. Oh yeah, plenty of soap is good too!

                          When you install windshield and rear glass, where do you put sealant? Given the intermittent nature of the bottom fence on the front, I am guessing sealant there. I was under the impression that sealant goes on both sides of the gasket.

                          I never use sealant between the glass and rubber. Only along the bottom before installing rubber and around the rubber before installing the chrome.

                          in reference to the windshield (front) do you put the gasket in the frame (locking strip type) or gasket the window /then pulling it into the frame with the non-strip

                          Many years ago, when I took my first 67 fish apart, I found the black butyl sealant between body and gasket all the way around both front and rear. Between the gasket and glass was off white stuff like the bedding and glazing compound used at yesteryears wooden framed house windows. When a helper and I went to a parts yard to get gasket and reveal trim from rear of a 68 notch, we found the same black sealant in both places. We took front trim and gasket from a different a-body (71 maybe). That windshield was broken out so too easy to pull what I wanted. I really don't recall what we found there. I know it took hours to clean the used gaskets for reuse. Couldn't trust them really so I put the black sealant everywhere. I've never installed a new gasket, so I really don't know what they require. Some of what Chrysler did back in the day could have been overkill too.
                          I've seen quite a few glasses in older vehicles get cloudy or delaminate and its always around the bottom of the glass. I don't know if the raw edge of the glass standing in water is the cause or not. Good luck any way you go about it.

                          I would think if you are “roping” the front glass in that you can’t sealant between gasket and fencing until after you rope it. Is that not how the front is done?

                          I used the sealant inside the gasket where it seals to the pinch weld all the way around into the bottom corners except between the drains ..I used 5/16 butyl tape there..pressing it down flat with the windshield in the gasket.
                          I already popped the trim on but I think I'm going to pull it ' it's got to be buffed anyways'.. and then run butyl tape all the way around metal to seal over the clip screws and backup the corners to keep water from building up and rust and to reinforce the trim ..especially in the corners.
                          No sealant between glass.

                          Forgot to mention that it rained on the car for 2 days and no leaks.

                          It would be cool if any MOD could combine this thread with my other for trim clip location. I start in one and end in the other.
