I tried to search for information here, as well as looking through the interior threads. What does the bottom edge look like? Is it trimmed to follow the bottom contours of the panel? The pieces that came with the carpet set are serge bound, and it appears they made them so the serge bound side should be cemented against the lower panel, which clearly isn't correct based on the picture posted. Thank you for the help. If you could post a picture less the floor mat It would solve part of the mystery. Thanks again.
