Hello, I just recently joined the Fiesta ST club and the car came with this aftermarket shift knob. I would like to replace because living in socal the all metal knob is gonna get hot. Anyway, for whatever reason i'm having a lot of trouble trying to unscrew this thing. I'm not sure if maybe there's a screw holding it in or what. Does anyone have any clue what kind of knob this is? or tips on removing it? Thank you.
