How do you adjust the vent window frame

Mike69barracuda said
My 69 barracuda passenger door vent window frame is preventing my passenger door window from going all the way up to meet the convertible top roof rail weatherstripping. There is more room at the top of the vent window frame to adjust it go up higher, therefore i'm allowing the passenger door window to go higher.

Here are some pics for discussion.

Oh that's not going to be fun those are a pain to adjust I'm pretty sure when you adjust the vent up you have to adjust the window track up with it. There adjusting nut at the very of the door I think it may have a plug over it. Take the door panel off and have a lot of time and patience
