can you take a picture just to validate the parts you are talking about. If its the pieces I'm thinking of, pop the shifter ring, undo two screws that connect bolt it in place and pull them out. But then again, I'm not sure what part you are talking about.
here is a quick vid my daughter and I did on swapping out the shifter knob. Are talking about the panel that has the white stitching in the very first scene?
