I just replaced some broken windows on my newly acquired 1950 F1. Before I removed the cracked vent window, I noticed that it almost overlapped the divider bar when closed. After installing the new glass, there is no overlap, but the gap is still much tighter at the top than the bottom. It's just a bit too tight for the seal that goes behind it (not installed in pictures) Is this something I can adjust out, or should I try and reset the glass in the frame? See pics.
