Just throwing this out there, I cant picture for the life of me right now, but if the plastic for the seatbelt assembly is anything like the plastic bumpers on the X, you could try a heatgun on it. I used a 1500 degree heatgun (paint stripper) on the outside plastics on mine to restore the color, I even had a spot where the rear corner bumped a tele pole and creased it, the heatgun made the creases nearly impossible to see, blended them right in. That was probably the beginning of LAST summer (2010) when I did it, and they still look pretty good.
