Do you still have the carpet ones? If so do they snap in? Could be as easy as the back of the mat snaps are bent. Compare the two if you have them. I would take a picture of the back of my mat snaps but I am not at home right now. You inspired me to go hunting for the slush/all weather mats and can you believe I found a new pair still out there! Well they say they have them we will see. Would not be the first time that I got my money back on something that was out of stock.
