Has anyone experienced problems with the bottom billet grill from Grilles4U? I purchased the set, top and bottom for my 09 CX7. The top fits ok, the bottom did not fit at all. The upper piece of the grill that should fit flush against the bottom of the black plastic, curves downward and away from the body of the car. I'm in process of returning the piece for a refund, Grilles4U said it was a design flaw and they couldn't fulfill my request for an exchange for the proper grill.
