Car is getting ready for body and paint and these trim pieces are the only ones yet to come off. Can someone tell me how to properly take these off as I don’t want to damage trying to take off.

 

The door trim has to have the vent window frame removed. There is a small screw behind the vertical support. Only way! The rest are clips that fit in oblong holes. Best to get a mirror and a long screw driver to get those. Once you get the first one to release the rest will just follow. Not an easy job. Had the door off and it was a pita. Quarter is easier but a pain.
Good luck
