JB,
I think the article gives a good description of what needs to be done and how to do it. I did both of my doors with the intent of restoring and replacing as much of the removable parts as possible. e.g the plastic and rubber, whiskers etc. I also thought that once I was in the door I didn't want to have to go back in so do everything you can do while you are in there.
The guides on mine had both fallen off and the glass was very movable without them. My tips would be to make sure you use extreme care removing the clips that hold in the whiskers and the chrome trim along the top of the door and don't bend the chrome trim, use epoxy to glue the guides to the glass so they won't fall off again, and be very careful when attaching the glass to the frame and don't overtighten the small bolts to avoid breaking the glass.
My last tip is take your time because there is a lot to do when you are in there...lubrication points, cleaning and final adjustments to the glass for proper fit and reassembly. Once you get it done you will be glad you did it. My ride was much quieter after and all my locks worked properly. Good Luck!!
