Does a seal exist for my factory 1977 c10 sliding window

[77Big10]

I just pulled this seal out of my 1977 C10 Silverado. I'm 95% certain it was the factory because it's so beat-up and had the matching aged chrome lock strip. I've been finding mixed answers on what is the best solution for this fix. I don't have a preference whether it has the Chrome locking strip or not. And if I replace it with a later model OEM sliding window, will that work, too?

I think I see a flat lip on the backside. That style (where there's a flat lip that goes in the gasket and then the glass is in a frame that protrudes out a bit) typically uses the same seal as a solid back glass. Hard to say from those pics, do you have any with it on the truck?

the photo attached below was before I pulled the window but I have a precision seal with the Chrome lock strip, and if I try it, it will not fit correctly. It does have a lip on the edge where it seats inside the seal it's probably a little bit thicker than an eighth of an inch

 

[TotalyHucked]

Yeah, that's just a regular rear window gasket like the solid back glasses use

So should I order a different one other than the precision one? Because everything I do I can’t seem to get it to fit right. Seems to be too big for the window

Nope, Precision is the best brand. They are a bear though, even my glass guy says how hard they are to install. I don't mess with glass cuz it's such a bear, well worth it to pay someone

@77Big10
Can confirm what huck said and your seal should fit.
Same as our 86 that I put new Precision window seals in.
Yes it appears to be longer than necessary or what will fit. But it does fit. Once the corners are fit in tightly and any “stretched” sections are relieved, it’s exactly the right size.
If it’s any consolation, the rear window/seal is much easier to install than the windshield.
And…nice looking truck!

 

[77Big10]

Thank you boss. I’m trying my best. I just get the joy of reassembling all of it after the fresh paint job.

So I notice the gasket fits 73-91. Will a back window from a 95 fit in an 86? Have a bead on one for cheap if it will.

That would be why the good Lord Lord made plasma torches, grinders and welders. I don't think they will. The square body dimensions are different than what the GMT 400 platform. Then again Chevy has been pretty good about not changing the glass for every vehicle produced.

 

[Bowtie-dad]

Agreed with precision. I use a quarts radiant heat lamp to soften the gasket and keep it on while installing and lots of dawn dish soap and water in a spray bottle. Just don't get too much heat on it

Amy leads for door glass kits for a v20 suburban? All the ones I find are cheap looking some look 3d printed. Door seals are good. Any help would be appreciated.

 

[brooksman9]

Looked at some pics of both online. The GMT back glass looks taller. Strange though that they use the same gasket. Guess I'll just have to buy one for regular price.

 

[Bowtie-dad]

I would try a company called Metro molding. They make custom cab mount bushings window gaskets 1/4 glass etc. reasonably priced to. If rubber Steele products, LMC or Metro molding doesn't have it, then I'd say it's your white rhino

They don’t. Not even remotely the same window or body style.
