Thanks for the help and ideas everyone. I have an appointment Wednesday at Apple to pull the glass and try to fix it. The glass is fine and I intend to reuse. The seal around the window was recently installed new by the previous owner after the new quarters were installed and car was painted etc. New clips were added to this 67 so that 68 trim could be installed.
I am assuming that the leak is because no sealant was used. Also possible the seal was bad from new or that the install was bad. I hope to see once we pull the glass. I'll order a new seal if the old one is compromised. The glass place said they have a guy familiar with these cars. I am surprised this type of seal could ever not leak without any sealant added? though I have noted that some have said they had success without sealant.
I looked at removing the interior parts but I don't want to unless I have too. Looks like the side panels below the back windows would need to come out to get at some way to pull those side metal pieces that run up to the headliner. the lower piece that runs along the bottom of the glass was easy. Everything else looks like a major project. ( I live for projects lol, just no time at moment)
ps I had tried to hose. Crawled in the back, folded the sea down. Wife put water across bottom, no leak. Started up driver side and not up very far and in came a stream of water. Leaks bad lol. Can't see exactly wear but not sure it matters. Hope it's fairly obvious once window and gasket are out
