in this picture is a black belt material that is riveted into the drive.
does anyone know what that material is and where can i get the material?
I think you’re referring to the black perforated plastic. That was provided in the KoP years ago, and came with some window motors and a window track. It was used as a power window drive. You can try GM parts or Chrysler.
