gear knob is a bit weird as im used to a big metal one in my other car but i thought the leather would go well with the gaiters that are in there and the steering wheel. yer there really simple to do as the gear knob just screws off and you replace it with another one... the ebrake a bit harder as you need to cut iff the old one with a stanley knife... i think the MOMO units fit well so thats why i used them straight on and fits 1st time
