It won't fit well, sell it to me!!
Sorry, it is a direct bolt on. Seeing as your current steering wheel is off it shouldn't be difficult to figure out how to slide the new one on. Just make sure when you park and pull the old wheel off it's aligned straight so it's easy to get the new one back on straight. You'll have to lock the column (turn the wheel to the right a bit to lock) to crank off the bolt holding the wheel on too. After that bolt is off give the shaft a whack with a rubber mallet and pull on the old wheel to get it off. Now slide the EK9 wheel on!
