Thanks - didn’t think of those guys. Steele has all of them except for the big side windows unfortunately.
On my Chevy I had 2 buy the rubber extrusion and use an exacto miter kit and cut the corners myself. 20 yrs and they still look good but now they are reproduced
I know it doesn't help you much, but mine appear to be set in a shit-ton of Permatex, RTV, or the like. I looked at Kanter, no luck on what you are looking for. Other choices to check are Eckler's/Mac's.
I was looking for the tailgate beltline yesterday, and found part #70-3178-77 which appears to be what you want for the side windows. They are listed under "1963 Ford Country Sedan 4 door wagon - 2 seat" but they should be the same on all four door wagons. They are $264.70 per pair, not too awfully bad. https://www.steelerubber.com/quarter-window-weatherstrip-70-3178-77
