New rear leafs too short?

I had the same issue. Bought them and tried to install 2 years later. I thought about prying them back but thought what happens when I hit a good bump and they flip and smash my trunk floor? Or will they settle down? I'll be watching :popcorn: . Would love to get them to work. Eye to eye they were 1" shorter than my saggy springs which didn't seem wrong as an old spring would be longer, I think. Maybe I'll install and let it sit all winter? :rolleyes:
Once the weight is on them, they will not flip back up.
