67 Fastback, mystery screws questions

I am finally assembling the interior on my 67 Barracuda Fastback. Two questions:

1. On the back flat metal shelf between the back seat and the trunk, there are screw holes on the bottom front that are for securing it to the floor, and there are screw holes on the top front that I have no idea. What is supposed to go there? (see pics 1 & 2)

2. On the floor console shifter bracket, the front left, is a mystery bolt. What does that bolt attach to?
