1986-1990 Caprice door panel removal
 

Seems impossible unless there is track. Pull handle is riveted to the door panel and a backing plate that is secured to the dorr with screws with no access unless you damage the door panel. I am sure there is trick to this. If you know it please let me know. Thanks

Remove arm rest. Drill out the rivets on the pull straps. Remove door panel. When reinstalling, simply re-pop rivet the pull straps back on or use screws.

Hey man! There are a couple hidden bolts under the padded armrest part. Also one screw for the window and door lock panel. After those are out of the way there are screws under those panels. As well as under neath the plastic section of the armrest.
Taking the door panel off you use a plastic trim pronged fork to remive the plastic barbs.
Good luck!
