I found one of the series of pictures of how to exactly remove your stubborn side windows in a 65-66 mustangs. There is a trick, here's the rough procedure below:
1) Roll the window down and remove the felt strips, the front and rear rubber door plugs.
2) Remove the armrest, interior door handle, interior window crank (keep handy so that you can quickly roll the window up and down.
3) Remove interior door panel carefully by prying near the clips with a flat bladed screwdriver (the wider the better) or interior trim removal tool (can be found from Eastwood Co.)
4) Loosen Front Vent window and remove all bolts.
5) Remove wire clips from the plastic window rollers and pull window crank arms out of plastic rollers
6) Remove all the window crank retaining bolts/nuts and remove window crank through bottom opening of the door shell
7) Grab rear of the window frame and carefully work the back part of the window out of where the rubber rear door seal was.
8) While holding window (or have a helper hold the window) remove the chrome front vent assembly and front window track.
9) Slide the window back into the door frame.
10) This is where most people get frustrated and stuck. Rotate the rear of the window 90 in the counter clockwise (DS) or Clock wise (PS) and work the tab on the window support plate through the gap where the front vent assemblies were.. Refer to picture below:
11) Carefully life the window the rest of the way out.
Reverse procedure for installation.
These instructions are to the best that I can remember here at work with no actual physical references. I’ll try and find the rest of the series of removal pictures later on.
I hope this helps!
