720 King Cab rear window seal wanted

Postby Justinberni » Thu Jan 28, 2016 9:14 am

yesterday I picked up w new solid rear window from Wayno, but now I can't find the damn seal for it!
The only ones I found for the Kc were $120-180, and that's just too damn much, so does anyone have one?
And also, if I find a used one in good shape is it okay to reuse them??

You can likely just use the seal that is in it Justin, but that depends on how old it is, and the temperature it is outside when doing the change, the colder it is, the harder the rubber becomes, the harder it is to work with.
When I pull the solid window out to put a slider in my 521s, I almost always reuse the seal if I can, it always comes down to if I am able to get it out without destroying the seal in the first place.
Have you ever changed a front or rear window before?

No I haven't, it'll be my first time.
A couple people said the rubber from my slider window is different then a solid window though, I'll probably go tear windows out of junkyard trucks and compare. Since it's winter, I'll probably take a heat gun to the rubber to warm it up, maybe that'll help?

It's easier when it is hot out, but it would likely help if the gasket was installed on the window and thoroughly warmed up inside a warm house, then taken out and installed in the truck before it gets cold.
I guess when I have pulled a slider out of a 521 at the wrecking yard I always try to save the gasket.
I just went and looked at all my 521s with glass and sliders, they are all the same gasket, but when I looked at the dually 720 gasket(solid window) and the slider gasket I have in storage, they were different.
You are likely in better shape though in your situation, I suspect it is easier to find a stock OEM 720 gasket for a solid window than it is to find a aftermarket gasket for an aftermarket slider.
Get one at the wrecking yard if you cannot find one anywhere else, the rubber has to be a lot cheaper than the glass itself at the yard.
I mostly deal with 320/520/521 glass, so I guess I just assumed that the 720 would be the same way, maybe not.

since it's not that warm out, try using some lubricant on the rubber to help it slip over the pinch wells much easier. Try WD-40 or maybe some soap in a squirt bottle or some awesome.

question- will a small cord be needed to help install the rear window ?

I install all my windows with the cord method with a screwdriver to help certain areas along, I don't like to pull on the cord very hard as I am afraid it will damage the rubber seal.
I do it slowly though, it takes me a while to put a windshield in, as I don't want to crack it.

When using the cord,trick is to rotate it in in small circles around the corners(helps prevent tearing)
A little dish soap on the corners helps too

The difference I've found between slider vs. solid rear window seals has to do with the width of the internal groove. Solid windows the groove is the same width as the glass thickness, sliders it's usually much thinner. This is because the slider frames have a much thinner flange around the outer edge instead of full glass thickness. This does apply more toward a comparison of OEM solids and aftermarket sliders in my personal experience.

Ran into this problem years ago when I took out my solid to install a Flex-Thru in an '85 standard cab 720.


These are also nice tools to use when helping the cord method.

They also have cheaper versions at Harbor Freight but I can't vouch for their strength like I can the ones in the link.
