I am restoring a 63 Impala convertible and I have an issue with the convertible roof rail weather strips. I have them installed but the window from does not latch properly it has to be pushed in and when I try to open the door the window gets stuck in the weather strips. Also there are some gaps at the ends of the window frame. Is it the window alignment issue or there is something wrong with the weatherstrip? The weather strips are reproduction, got them from classic industries, I didn't have any issues with any of the other weather strips except this one. Any help or input would be greatly appreciated.
