I ordered a new lift gate from Marco because the old one cracked and finally fell apart. When I got the new one the holes that the screws lock into are too big. I would use a slightly bigger screw, but the screw have to go through the metal L brackets. Has anyone else had this problem with a new lift gate from Marco or is it a defect I should send back? If it's not a defect, any suggestions for fixing the problem? Thanks
