Window Frame Part needed

I am in need of the metal peice that connects the window frame of the drivers door to the bottom of the inside of the door. I hope I am somewhat making sense trying to describe what I need.

The passenger side one was there with the car, but the drivers one was missing and a long bolt was rigged up in its place. IT doesnt seem to hold the frame in place as good, and I am trying to get the window to line up the best I can

Thanks,

Shane
