The handle droops most likely because the screw appears to be missing that secures the door handle in place. It’s possible as well that the spring inside the latch assembly is broken. Note there are two springs. The one shown in the attached photo, on the right side of the assembly is the “anti-droop” spring. The second spring is near the center of the assembly and is part of the latch mechanism.

The door panel hole is used to secure the door handle. See the first photo below. The ‘46 door panel on my ‘46 is shown in the second and third attached photo.

The door striker photo in your post appears to be well worn, possibly worn out?
