I am pretty sure some of you may know this already but just in case you didn't, here it is. I went to the Junk Yard today and I found a 78-85 Mazda Sundowner truck with pretty good weatherstripping for the doors. I noticed that the upper half of the door frame is exactly the same size as the one on the repu. I got the vent window and all the weather stripping from it and it fit perfectly. I took the upper door frame off the truck and went to a 74 Ford courier and tried it, it fit just like the original but it wasn't as rusty. Next time I go I will check the windshield seal because I found a couple of Mazda sundowners with the chrome trim for the front windshield.
All the rubber interchanges between the Courier and the Sundowner/B-Series/REPU. The only exception is the rear window from 77 on.
