I have also had success with gluing the "windwings" with mirror adhesive.

I have the one's with the lower pivot screwed on, the upper pivot glued, and the latch glued. Mark where the latch needs to mount. Take the window out. Clean thoroughly both mating surfaces. No abrasives, just clean and flat. Mount the latch. Wait 24 hours. Remount the window. Apply glue to upper hinge area. Clamp for 24 hours with the window open and unloaded.

Then just be careful when you operate the window. I always use 2 hands to minimize the forces on the glued parts. Tell your passengers you will open the window for them!

Back windows (142): easy upgrade to the screw-type latches.

Good Luck!
