Help me help you Seal fitment, Started a new thread to deconstruct this Options

[Mikey914]

This was brought us as an issue and I'm really trying to figure this out. Any ideas of why the window would look lower and have a gap here.


Here were my thoughts -

I keep looking at this and something doesn't look right. Given that the blocks are identical to the factory ones in shape and durometer, what would the solution be here?

There appears to be a 1/2" section of rubber not fully seated, Is it holding it out?

Could the amount of butyl behind the "chrome" be holding it down slightly? I don't think that would be the whole story.

The triangle window looks like the top is seated deeper than the cap. Almost like if the top of the triangle window was shimmed out more it would push the bottom of the cap out more to "close the gap". This appears to be where the failure is - at least in my eyes. I've seen many of the caps worn and look slightly deformed from the top of the glass pushing it out, but not here. It looks like it's barely engaged.

Why it would sit lower is beyond me. The initial complaint was it was too tight, which would hold it up.

Just a word or caution. It's not just about whether or not the window cap triangle fits into the windshield header radius.

As was the case in Bbrock's original post, it's about whether or not the seal is actually sealing to the window and the triangle - sealing out water and preventing wind-noise.

In my case, when I was able to get the seal fitting into the windshield header radius, it does not simultaneously seal. If you are on the inside, you can look out and see a sliver of daylight.

Like Brent, I feel I could get a better seal if I could shorten the window channel a smidge but the way the adjustment is you either get an inboard outboard adjustment or a fore/aft adjustment. Each alters the height of the channel ever so slightly but not enough to make a difference to the fit.

Unfortunately like a couple of other pictures here, I didn't take one showing the visible light gap between the seal and the glass / triangle. You have to be at just the right angle to see it and/or be inside the car looking out to a bright exterior - but the gap is there.

Tipping the window channel inboard just results in the seal pushing it out and increasing door closing efforts yet the seal gap to the triangle window and window cap never seals.




This is a picture before I was "finished" but the amount of glycerin all over everything speaks to how much fitting, refitting, etc., was required and it gives a view that the window channel seems just a bit too high. Also dimension "f" was verified throughout my build at 25 1/8".

In the view below - this is before the window channel was moved inboard as show above.
