Year One came through in a big way. Among other things, they supplied carpet and all the weather stripping for the car, which kept the elements out. They also supplied sound deadener and the rear seat divider; both of these contributed significantly to less road noise. Other Year One items included a fresh dash pad, carpet, sill plates, kick panels, sound deadener, body plugs, and a lot more. If youre replacing the carpet, you might as well spring for fresh plugs to keep the carpet dry (and fumes out).
