Mine are fairly straight too, but at the top, about 2" from the end, there is a slight bend toward the outside of the car, but mine is an aftermarket frame.
Hard to tell in your pics. if yours is bent in the same area.
The arm that connects to the top and then to the large bracket that bolts to the side support has 2 bends in it. The one at the top end starts about 3 inches from the end. It is not a lot, but over the length of the arm it will pull the bottom closer to the support. The other end has a bend on it as well, it is not as much but just enough to rotate the angle of the lower bracket to bolt to the side. If you put a straight edge on the center of the arm you should see both.
Also the top end should have a rivet in it. The fact that it does not leads me to believe it is not OEM.
