Re: Half a dozen failed windshield install attempts...
 

Hey dave, sorry to read of your troubles.

Back before I learned of this site. I broke 2 windshields(1 new one and 1 used)one trying too get them into the kids 67 with no trim.
On our 3rd attempt with another used sheild it slid rite in ezpz and in short order.

I had no experience in these in these yr trucks then . But I did succesfully manage to get one into a 77 and a 82 I had way before.

Somewhere I read on here KY jelly works good. But I don't know if it's the same ingredients as vasaline.

I have a new one sitting here for my 67, kinda been worried about the install day on that one.

Re: Half a dozen failed windshield install attempts...
 

I've heard vaseline is bad for latex, they taught me that in health class I think. But I don't know about rubber, so I used a fair bit of vaseline this time around.

In some ways it made things harder, as the window slid around very easily. On the other hand it made things simpler to align and center, for example. So on a future install I'd still recommend it.

That's how hard this truck is to install glass into. I'm not making this up, I had a witness :-)

When you're the second or third guy to deem a truck impossible, you know there's -something- off about it. Just don't know what. Maybe Jesse that I bought it from chopped the top half an inch like he said (in jest).

Any petroleum product will degrade rubber over time, so you should prefer a silicone type of lubricant instead.

Re: Half a dozen failed windshield install attempts...
 

Use soap or glass cleaner. Silicone will make it difficult to get a seal with butyl-based sealant if you have any leaks.

Re: Half a dozen failed windshield install attempts...
 

Good point, never thought of that. If there are leaks, is it common to shoot some butyl-based caulk into the seal or something?

Re: Half a dozen failed windshield install attempts...
 

We used to lift the rubber with a glass stick and squeeze windshield sealant from a tube under the rubber if they leaked. As far as rubber set windshields go I have replaced a lot over the years while doing body work and I worked in a GM truck dealership in the 70's. The only one I ever broke was one of these trucks. You need to be sure the bottom is in and all the way down before trying to pull the top corners in. The 73 and up shields seemed to just drop in after dealing with 67-72's.

Re: Half a dozen failed windshield install attempts...
 

Yes, the recommended sealer is a flow-grade butyl sealer. The factory specified sealer at the top corners, but you don't necessarily need it. I only use it if I find a leak.

Dave
When you get this worked out would you mind letting me know who you had do the install? I have fogging around my window and would like to get it replaced, but would like to find someone that knows what they are doing, including keeping the chrome trim.
Thanks

I'm taking it to Euroglass in Redmond, they're a high dollar shop (does all the Bentley, Mercedes, Audi stuff) but with techs old enough they still can do our trucks, and they still have the tools and knowledge to replace the glass in the quarter windows, that sort of thing.

It not that doing all the high end import stuff makes you special - but keeping that business for decades when those customers are picky, that makes you special. Anyone can do it for a while.

So I'm told, and Yelp agrees, but we shall see when they meet the test of "Dave's Truck", and I'll report back.

Drove it yesterday with the new glass in it, it's a world of difference from the tint band that was in it before! Definitely worth the hassle.

Re: Half a dozen failed windshield install attempts...
 

Sorry to hear you are having so many issues Dave. While reading this, I realized that I might have forgot to update the other thread with how my windshield install went. I know you probably don't want to hear this, but it went really good. I had an experienced installer do mine, while I helped. As you might remember, I used glass from Summit (bought the same one that you are using). I also used a Precision gasket. I did have to use the OE trim that I had though. The brand new aftermarket stuff would not lay flat on the windshield no matter what I tried. I had the gasket and trim on when he got there, so luckily I was able to get my old OEM stuff and polish it up really well. I think it actually looks better than the aftermarket. As far as the window goes, we had no issues at all. It was thinner than original, but it fit fine. I do have one suggestion if you have not already tried to do so. That would be to get a second window seal. Maybe your first one is just bad or something. For the price of a a new seal, it would be worth a try and might save them some time. Good luck and keep us posted.

Re: Half a dozen failed windshield install attempts...
 

I remember the whole problem was looking through the tint.

Did you ever mod your seat too get it lower?
Just curious if ya did and what you did too it?
Cause I have the same problem in the kids truck with the bench.

Re: Half a dozen failed windshield install attempts...
 

There just wasn't going to be enough room. I still look almost dead straight through the top of the tint area and I could never get that much room out of the seats, so the windshield was my only real choice.

If I could have dropped the seat 4" that would have done it, but I don't know if that would have even been a good idea!

Re: Half a dozen failed windshield install attempts...
 

I am looking to get my windshield replaced on my 72. I've called a couple of places and they keep on saying that I should only use the gasket as there isn't a good seal with the trim. This doesn't quite make any sense since I've seen the windshield sold with the gasket and trim.

Re: Half a dozen failed windshield install attempts...
 

By trim do you mean the stainless? The stainless is harder to install and takes more skill, but that's the only reason (to make it easier for them) that I can envision for leaving it out. I can't imagine it effects the sealing in any way...

Re: Half a dozen failed windshield install attempts...
 

Yup that's what I'm talking about. The stainless trim. I figured it would be more work and not really because it would damange the sealing.

May have to look into doing it myself to make sure it gets done correctly unless there is a rec for an installer in the Austin area.

Re: Half a dozen failed windshield install attempts...
 

I recently added the stainless trim to my front windshield and boy was it a real pain in the a** to get the window back on. It took my buddy 3 hours and he does this for a living. I was told as well since I had the wrong gasket the first time. 67-70 use a different gasket/stainless molding than 71-72. After going to the Truck Shop in OC they sold me the correct gasket for my stainless and everything fit nice and tight. No fighting with trying to get the stainless to stay on the gasket and window. Anyways I'm glad I wont be doing this anytime soon again. :)

Re: Half a dozen failed windshield install attempts...
 

Since the cabs are the same, if you have a matching gasket/stainless for 67-70 or 71-72 then all should be well right? Any idea what the difference in sets is and which is better/easier to install?

Edit: http://67-72chevytrucks.com/vboard/s...d.php?t=649472

I guess the 67-70 is easier to install and yet either will work as long as the gasket/trim are for the same years.

Re: Half a dozen failed windshield install attempts...
 

The way to save yourself a TON of install issues is to install the gasket and trim onto your new glass and use 2" masking tape to hold everything in place and let it all sit for a week or 2 to let it settle and live together . Sounds funny but it works a day or two in the sun works also .taking the gasket out of the bag and stretching it onto the glass and installing the trim forces the gasket to become "alive" while it searches for its happy place ... try it .

Re: Half a dozen failed windshield install attempts...
 

Hey utee, Let me know what you find out about windshield installers for our trucks in the Austin area. I need to get that done as well. BTW, nice truck!

Re: Half a dozen failed windshield install attempts...
 

I had to drive a vehicle without a windshield about 30 years ago.The local pd told me it was ok if i wore eye protection so i strapped on some safety goggles and drove it. the law could have changed since then.I didkeep the speed down afraid i might blow out rear window

Re: Half a dozen failed windshield install attempts...
 

i feel for ya. just did mine only i got rid of the trim. it was still a couple hours with a lot of dawn dish washing soap. the back window was done in 30 seconds. got my gasket from classic parts with out trim. the worst part where the top corners. there is a vid on utube they did one like ours with trim and they started at the top and fought the bottom. its that double lock that makes it a pain but once done it will never leak. good luck and watch that vid even the experienced had trouble.https://www.youtube.com/watch?v=SOU_0HpS7To
