The rubber seal that goes between the aluminum strip and the windscreen is causing me grief. The seal I removed I believe is original. Although deteriorated in sections, it was surprisingly good in places, so I feel I have a reasonably good example of what was there. Also the ends appear to be molded in a curve to match the aluminum strip, as opposed to being cut as a replacement would be.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>This (possibly) original seal was a solid piece of compressible foam rubber about ¾” wide and appears to have tapered in thickness, from ¼” to 3/16”, although this seems unlikely. I recognize that 60 years of compression makes exact measurement impossible and uneven compression may have made it appear tapered in section.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The replacement I got was hollow and narrower. Compressed slightly, enough to just squeeze the hollow centre closed, it was ¼” thick. However, when I installed it, the top bow would not go onto the windscreen without a huge amount of effort and force, and I was never convinced it was on properly. The top bow always used to fit on the windscreen snugly and with ease in the past (I have owned the car for 46 years). I don’t understand this, as the new seal when compressed would seem to be the same thickness as the original, but “the proof is in the pudding” – it does not fit!<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>To experiment, I cut the replacement seal to half the thickness, so it is now 1/8” thick, and the top bow mounted on the windscreen with ease. So the problem is the seal. However, I think 1/8” is too thin and it will likely leak.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span lang=EN-CA>The Concours Guide, Supplement 1, page 5, provides a photo of a 100 seal, but it is silent on whether this seal was carried through to the BT7 or was changed at some point.
