Window a little off track.

Hi guys, just a quick and hopefully simple question for you. My left side window in my 66 coupe has come a little off track and i was just wondering how you take the door panel off to have a look at it. I havn't had the time to check it out myself at the moment but i thought one of you guys might have some advice on this. Thanks for any help.
 
Remove the window crank handle and the door latch handle (Both should be allen screws), remove the arm rest (two phillips head screws underside), then pop off the door panel (be careful not to tear it up). More than likely the problem is with a worn out roller coming out of the track. If thats the case, be sure to change all the rollers in the door (less than $1 apiece at any auto glass shop)...
