Perfect fit for my 2007 Honda Civic EX coupe. Use a 2mm allen key as a reference. There are many installation videos. My advice for removing the plastic cover from its storage position is to use pliers around the shaft under the plastic spacer and then use the lever to twist up to remove the plastic cover. To put on the Short Shift Adapter: Place the cap on the ground and push in the Short Shift Adapter. Use a towel or shirt to cover the hole with a stick while you work to avoid the hassle of searching for dropped parts.
