I drive a 3 Door Freelander, and noticed yesterday In the rain that water was running down the pillars in the middle of the car where the front seat belts attached, I quick inspection of the top of the car, under the flaps where you can attached the roof bars there are 2 holes, I assume this is where the roof bars screw into, Mine does not have roof bars, so those holes are open to the elements, I can only guess is running off the roof into these holes then into the car ? If so, any idea where I can get 4 bolts that will fill those holes in ? Thanks
