I ended up doing something very close to what RedBarchetta suggested on page 1. I first bought the BB Bailey Mat-Locs. At least for me, they are hard to install on a Superformance. After I got one installed on the driver's side, I started thinking that they might not stay secure over time. In my studied effort to avoid contact with side pipes (burned once, now forever cautious), I put a lot of weight on the mats getting in and out. The anchor mechanism is a small diameter pin stuck through a layer of glued on carpet. So, I went to Lowe's, bought a grommet kit and some 11 inch black cable ties (both cheap). I installed two grommets on the back side of each floor mat adjacent to the metal members that anchor the front part of the seats to the frame. I strapped a cable tie through each grommet, looped the tie around the seat anchor mechanism, tightened the ties, and clipped the surplus tie material. The grommets and ties are not readily visible. The mats are now solidly anchored and will never slide forward again. If I ever want to remove them, it's a simple matter of clipping the cable ties and reattaching with some of the extra ties that I have kept. Again, great thread. Thank you for all the excellent ideas and suggestions. Larry Carlson
