When you replace the friction stays on an upper window with limited or no access from below it's a good idea to put a ratchet strap around the window while you're working on it so you can't drop it.
Once you've established the length of the stay it should be easy enough to pick up a pair and change them over. I've done a few that have side return extensions below them hence the strap tip.
