I just purchased a new 2010 Silverado 1500 WT. Naturally it comes with the rubberized floors. I purchased a one-piece carpeted floor mat for the front floor. Fits great but still moves just a bit. Most cars these days come with the "floor anchors" that your mats attach to (and most mats have the small hole pre-cut for that). Can these be installed in my truck without hurting anything. I assume they would just tap into the sheet metal in the floor. Thoughts?
