41 Ford Pickup cab question

[Tex41]

Restoring a 1941 Ford Pickup and upon removing the hood, hood braces and fenders I have questions about the holes in the side of the cowl. I know the top two and the one in the very front is where the hood braces connect. My question is the other three (next to the curve), especially the lower one. I see a rubber bumper in the upper most one of the three, but what goes in the next one and the lower one.
