These jacks work incredibly well for the rear jack on our 1996 RWD 4-door Chevy Blazer S-10. They fit perfectly. Now when you press the unlock button the window will appear by itself. They are really strong and sturdy and seem to last a very long time. I hope to be able to replace the last pair. I have had to replace them several times over the years and this seems to be the best quality set I have come across. I would highly recommend them to anyone who needs to replace their rear liftgate window stays.
