Thanks for the reply Mr Spadaro , can you or someone help with a picture of the channel you speak of. I have 2 cabriolets and none have the channel on the top post or the windscreen post. I have seen some sort of L weather strip and have tried a few I have picked up and work ok but want to be correct and seal her up tighter yet. We hope to drive to CA and the wife would like a drier ride

.
Thanks
