Before slipping the column in the car, we installed the included billet dress-up kit. The tilt lever just threads in while the turn signal and hazard components needed hardware (which is included) to be installed. You can use a stock turn signal lever, but you will need to be careful using a stock tilt lever. Some of those have longer threads that can dive too deep into the column and cause damage. So be very cautious and make sure the lever matches the billet one provided, or just use the billet one.
