In case anyone is interested, I just received my replacement floor mats from American Muscle. They were dropped shipped from Auto Custom Carpet and they included the two back seat mats. They are high quality and matched my parchment color interior to a T and the fronts are exactly the same dimensions as the stock ones. I had prevviously ordered the accessory mats from FoMOCo and I had to return them since the fronts were smaller than the OE ones. Go figure.

 

FWIW When I put aftermarket mats in my 07 GT Vert I had a problem with the gas pedal hanging up on the edge of the matt. Scared the crap out of me. Ended up turning the ignition off till I figured out the problem. I have trimmed the mat and eliminated the problem. Not saying you'll have the problem but check the clearance between the gas pedal; and the edge of the mat.
