Sholud be fairly easy to do fella, although I haven't done it myself.
You'll need to remove your gear knob by loosening the nut beneath.
Next you need to remove the centre console which holds the gear gaitor. You can do this by sticking the car into third gear to give you some room to manouvre.
Then hook your finger into the bottom of the gaitor and you should be able to lift the bottom of the console away slightly. Cover a knife with some electrical tape (to help prevent chipping the paint work) and gently prise the rest of the consle away from the housing.
Don't pull the housing away too quickly as you will need to disconect your ciggy lighter and hazzards button.
Then I believe it will just be a case of unscrewing the old gaitor and replacing it with the new one.
Hope that helps.
P.S. If I were you, I would find one with just red stitching and without the Type R logo. Just my personal taste though.
