Backglass install problem

I just knew you had to be working on a Barracuda Notchback, thats why I had to ask. Can't relate to the locking strip problem, I have 68 Barracuda Notchback and this year never came with one. But on the other hand, the issue your having with the headliner teeth, I had the same problem before and even after putting a new rear weatherstrip and a new headliner in the car. Seems to be a void running along the top where the headliner and gasket meet, one would assume either the gasket or the headliner would cover this area. I'll wait to see Rbob if you have an luck with your car.
