I have a 1996 dolphin with 1 slide out . a couple years ago I had a roller for the slide come apart. since then I have replaced the roller but I just noticed that the hard plastic that lines the floor of the slide out has been broken . does anyone know where I can get a replacement for it ? it rolls fine but I did notice a hick up when the slide goes out and in and it was due to the roller having to deal with the difference in thickness. Any help would be greatly appreciated .
