I believe Diesel means the sliders In-Channel and divider Glass Seals..... Honestly from what I have seen, those are mainly found through a Auto Glass Shop or Slider Manufacturer, but generally what needs to be replaced, usually ends up costing more than Having a New Assembly installed... From what I was quoted from the Shops around here, it would be about $85-120 for just all of the seals I needed, yet a new installed assembly would only be $185.... I know alot would want to keep their pieces for "Factory Correctness", but the Assemblies were made by an outside manufacturer, which is Generally the same one who offers the current ones...
