Window seals question

[brokestudent]

I have pulled apart my drivers side window, and of course every rubber seal is trash. I have cleaned the windows buffed them out etc etc and they are looking great, but now I want to paint and put back together. I want to obviously replace the seals, and I can find most of them. I cannot seem to find the seal the touches the glass and the frame of the vent window. Not the seal that goes around the frame of the vent window, but rather the one that goes in it and holds the glass in place. It rides around the curved edge of the glass as seen in the picture and sits in the channel of the went window frame piece. I would certainly entertain any vendors that make the whole kit or if anyone knows of a place that has the hole kit, particularly the part I am needing for a 1963 pickup please let me know.
