The spring with the hook on it is where it will be, it is located by where the other end hooks to the shaft. The kick clip can turn on the gear. The spring with the hook, the hook attaches over a post at the top and a bit to the left. The kick clip hooks into a notch in the case at the bottom. So I guess to answer your question the kick clip, with the shaft facing the other way, the hook of the spring up and a bit left the kick clip should point down.
When you try installing the shaft you will see just where the kick clip goes.
In your pic the end you see goes in first. The spring that has a hook on one end. As you slide the shaft in this end hooks over a post on the case. The kick clip fits in a notch at the bottom.
Now as you slide the shaft in it will stop when the "keyhole" shape will hit the case. Now you need to turn the shaft counterclockwise while pushing it in, about 1/2 to 3/4 turn. This gets the Keyhole shaped part in the recess it fits in. You will know your far enough when the shaft slides in all the way.
To turn the shaft slip the kick lever on the shaft.
Once all the way in you carefully remove the lever, being sure you don't pull the shaft out.
