My daughter has just got her first car a 2003 1.2 dynamique which she absolutly loves. However the person who had it before put a ripspeed gear knob on it now she wants to change it for a Richbook emblem gear knob. Can any one tell me how to get the ripspeed one off? it has 6 allen key bolts in the top Ive taken them out but it doesn't seem to loosen the thing. I don't want to start pulling and twisting it incase I bust the gear stick.
