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. Submitted to the brain trust Attached thumbnail(s) |

From my fitment:
I think in having to close that narrow channel gap, and getting the targa to seal to the header, the seal moves forward which then puts a portion of the harder "corner block" in a situation where it is now starting to engage with the aluminum header channel. And more of that harder corner block now has to engage with the top of the triangle cap? Moving that corner block of the seal forward also involved cutting about 1/8" off the tab of my aluminum channels that fit inside the corner block. I actually felt like I probably needed to cut another 1/16" off since I could still see that the seal wasn't quite as far forward as it seemed to want to be in order to get the seal to engage the bottom corner of the windshield header - yellow highlight. I didn't like having to trim the aluminum tabs at all but that seemed the only way to get a reasonable fit. I still wasn't thrilled with the fit in the yellow highlighted oval. It seemed like there wasn't quite enough rubber there. As a result of moving the corner block forward to get rid of the narrow channel gap, it seemed to me that I was forcing too much base of the seal into the aluminum channel which then resulted in a sort of buckling/compression of the corner block that is shown in the orange oval. It sort of tries to roll that area of the seal inward. (IMG:style_emoticons/default/confused24.gif) |
