1965 Mustang convertible door window regulator?

Anyone with hands on? My window was very hard to open and close. Decades ago I had the guts out of the door and figured that the tracks just needed to be lubed.

I finally pulled off the door panel and yes, the rather undisturbed lithium grease had hardened up over the years of inactivity.

More importantly, the rear arm had pulled out of it's roller. I squeezed the clip so it would take a better bite and reinserted the pin into the roller. I re-lubed the three tracks and all the pivot points I could find, then I sprayed dry lubricant into all the vertical glass channels.

The window works more smoothly now but when it gets down to about 3" from being closed it comes to a sudden stop. If I roll the window back up, then lower it with a small amount of pressure on the top edge of the glass, the window smoothly goes all the way down.

What might be going on? Is there a hitch in the quadrant and sector? Do I need to pull it to find out what is going on?

The rubber bushings that ride in those tracks are really cheap, and a replacement set may at least help your problem. If your track is broken like 6T6Coupe's, then you might have to cut a hole in the door for access, then weld it back up. If you do this behind the removable door panel, then it will only require a quick spray paint job to cover the welds up.
If that were the case, is it a matter of adjustment to make things clear? With that little bit of pressure added to the top of the window, it goes down smoothly like there is no hitch in the quadrant or sector shaft.
Odds are Veronica is right. If that is in fact the case, you might just need to reach in there and bend the bracket slightly. Normally, this is not a good idea since it could lead to things getting out of alignment, but since you only need to add a little bit of pressure to your window to get it past the sticking point, this method might be just the ticket. :)

6T6Coupe, was your car in a wreck where the door was damaged? Or did your bracket break at a poor weld? I have my door panels off so I could pull the handles so my doors could be painted. I am going to take the opportunity to clean and lube my slides and channels.
If it does not effect your enjoyment of the car, then put it off. Might be a good excuse to pick up a MIG if you don't already have one. :)
