I got my car back from the painter and he had disassembled a lot of parts including removing the windows. I'm attempting to put everything back together and using the Oldsmobile manual. It looks like I didn't get all the parts back from the painter. I can't find the lower inner sash channel filler and support. I've tried finding those parts on OPGI and on Fusicks but had no luck. Are these still available and if so does anyone know a part number. I'm attaching a couple pictures of the part that I do have and of the assembly manual page..
