I really don´t know if is the proper knob, what I know is that is original except for the red color of the sawing, may be a not-oem similar to original knob. I wish I coul take if off by unscrewing it, but I can´t take it off. I´m considering drill a hole and isert a srew to keep it tight, unles you or somebody else can tell me how to take it off. Regards
