Here are the links to the Jim Carter parts i am trying to install
Window Channel - http://www.oldchevytrucks.com/cart/product.asp?prodid=WI203&i=10946||||| and it is part number WI203
And the vertical strip - this is a Steele Rubber part -http://www.steelerubber.com/rigid-run-channel-60-0073-58
The window channel looks like it will fit, but i'm having trouble getting the vertical strip to fit properly. I can see U-channel of thin metal, riveted to the wing vent divider. Thank you so much!!!
