Patriot 88 window replacement part help

Hi, I just recieved new spiral balancers (part S600-20) and pivot shoes (part 15-015). I can see now I need the swivel bar and its holder that go into the bootm of the window. enclosed are photos of the reciever, but the bar itself was completely corroded. Can you help me identify the replacement parts for each of these components? Thank you, John
