72 Charger lower door panels

[auxiliarytwin]

Hey all,

I was wondering if anyone knew what (bolt/nut, clip, etc) was used to secure the lower door panel to the door frame from the 2 upper middle holes just above the arm rest.  These holes are not threaded, just open.  I know it isn't clips from the upper door panel because they don't line up, and I need to fully secure the lower panel before I install the uppers.

Any help would be great.

Thanks!

They go to the door with 2 rather large screws to secure it for pulling strength. They are just large phillips head screws similar to this one.  The other open spots are for the upper door panel clips.
