I do not think they were for the visors, but if so, the headliner is already installed.
They are pretty heavy brackets, so they might be for extra reinforcement in the floor, but I do not know where.
When I got the car, in 2003, most of the floor was gone, these brackets were attached to something, but I don't remember where. I blasted and painted the parts, and they were put in a box with a bunch of other parts.
I said to myself,......"self, you can remember where these go, no need to mark them".....
