I just purchased OEM rubber floor mats online from a LR dealer for my 06 LR3 HSE. I am wondering why there are not anchors built in for the part of the second row mat that extends toward the back of the vehicle. The mat clearly has a place for them. Also, there are two anchors in the second row floor, but there is only one hole in the mat. One anchor in the front seat popped off, so I am wondering if the same happened to the rear side. But there is no evidence, as in the front, that any anchors were ever present. Is it possible to have anchors put in fairly easily?
