I'm not sure what kind you have but on mine, once you put the top in (the top has a 90 degree bend in it to hook into the slot on top and the bottom part just goes into the slots on the bumper part. It's hard to imagine they could pop out) Can you take a pic of your setup by chance? If they came out.........I'm surprised the slide rails did not bend.
