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) |

i'm starting to notice some things here.
starting with. 1) roof to windscreen seal. that doesn't look quite like my factory seal. or at least my 74 factory seal. see back on page 2. my factory seal does not seem to have that single large curve bump at the windscreen frame edge like the examples you guys are posting up. where its running across the top of the windscreen. ??????? since this is all a one piece seal bonded at corners (? have i got that right) i think the problem you guys might be having is that roof seal portion is kind of dragging the windscreen pillar seal backwards towards rear of car out of the pillar. because it won't compress nicely when it gets to either end of windscreen top. as well i'm looking at my factory seal and it has a very elaborate kind of double-back mitre where they joined the windscreen pillar moulding to the top moulding right up near the top corner there. its a very tricky little joint in the original factory moulding. assuming it is a joint. i'd have to study it more. it sure is more complex than an 0-ring on a space shuttle booster. maybe i am not seeing things right with the 914 rubber seal in some of these photos here? @mikey914 . there is devil in the detail of the moulding itself that lets it negotiate the corner and rest at ease? i was peering into the interior of the corners of that seal on my car thanks to you guys. had a (IMG:style_emoticons/default/biggrin.gif) . factory workers hacked a good portion of the interior liner away where you can't see it to do a bit of japanese origami and not foul or push against rubber seal in any way ! never looked in there before. classic shadow detail. hides a million sins if you don't look into infinity. (IMG:style_emoticons/default/biggrin.gif) one last thought. the upper windscreen rubber is just the right dimension to be slightly in tension (or stretched) in order to pull those top corners in and never let them push out, even a tiny amount. i dunno. |
