I've installed new deluxe door panels in a 69 fastback. The panel is retained by the door panel clips and the 4 screws for the speaker grills. I am getting conflicting reports on if there were originally screws through the carpeted portion of the door panels into the doors and/or where should they should be located. There are no holes in the new door panels for screws, there are no holes in the doors to screw to (however the doors are not original to the car). Pictures would be greatly appreciated. Thanks in advance!
