Help!..., My rear windows are kind of stuck

I have a 69 and every time I try to roll up both of the rear windows I have to "rock" them back and forth to get them to come up. (seems like they are off a track or something)

The window crank and mechanism seems ok. I am not sure if there are guides in there or not...just figured I would ask before I crack it open......

anybody have any ideas or guesses on this one?

YOU PROBALLY NEED TO REPLACE THE ROLLERS
ON YOUR WINDOW REGULATORS. HAD THE SAME PROBLEM ON MY 69

i will probably tear the back seat out and the panel next week and checkit out. are those rollers part of the roller assembly or are they seperate? i think each roller assembly goes for around 75 bucks.....

thanks.

You probably won't need to replace the whole assembly. I was able to get mine working well with new rollers (couple dollars) and some silicon spray lube.
