Last minute update. If anybody prefers the plastic snap fasteners to the black metal grommets, they can be replaced. I gently .... Carefully pried up the backing plate of the plastic snaps and they popped apart without too much damage. Then I removed the metal grommets ruining them in the process then snipped out a bit of material in the new mats as the plastic snaps have a bigger hole punched in the mat then the grommet end ones. The plastic halves pressed back together into the new mat perfectly
