On my 65 the driverside vent ( wing ) window won't stay open by itself, My Question is ? How do you tighten ? where is the spot located to tighten ?/ Gary / Moz
When I took off the whole vent window assembly to install weatherstripping I had to take off a nut on the very bottom of the window which adjusts the window tightness. As you can see by the picture there is a spring above the nut. Takes a little while to get the vent window out of the door but it'll be worth it in the end. Good luck.
