I need to replqce the upper arm holding the lamp

Hey how you doing! I found a replacement bulb for you for the Hampton Bay 1327 (http://lampinfo.com/hampton-bay-lighting-and-lamps.php). Haven't found any other parts yet though - I'll keep looking!

I need the nut gizmo that connects the upper arm to the vertical piece... if the guy above can't find an arm, he can have mine if I end up needing to throw the entire lamp away.
