Sorry Dan, but I am going to hang on the lamps so I can put them back if I sell the car.

Never seen a Crossfire with the blanks, we only get one trim level of xfire here, no 'base' just the equivalent of 'your' Limited. I guess I could have ordered them through a dealer if I had known they existed but they don't even seem to carry brake pads in stock! The duct will actually be a long molded duct from the face through the bumper and exiting beyond the access panel in the arch rather than just a hole in the faceplate. Plus it's often difficult to get the polyprop. bumper material to blend with the polyester filler/resin successfully long term. Thanks for the suggestion though.

Simon.
