Desert Valley Auto Parts in Casa Grande, AZ has one. I just saw it today, but it might have some scratch marks from the window regulator pins dragging on it as it was pulled out. https://www.dvap.com/salvage/1965-galaxie-station-wagon-4dr-65ga1567/
We actually got the rear glass for my roommate's 1965 Ford Country Sedan here: https://www.sandersreproglass.com/ . You'd be looking at about $160 plus shipping from Vancouver, Washington. He was able to have the Carlite logo added on for a few dollars more.
