2.0t03speed said:i have a kartboy shifter in my 03.5 msp now. and the 03.5 shiftknob would not thread onto the kartboy shifter thats why i have the all back kartboy knob. even if i could put the 03.5 knob on i dont think i would because the kartboy knob is so ****** nice, and feels alot better in my hand than the 03.5 imo. but they dont make the shifter or the knob for the msp anymore according to there website last time i checked it was discontinued, but i could be wrong.
