Carefully remove the tail section body work. Save all bolts, washers and plastic rivets for re-installation of tail. Disconnect and remove the brake light (with all mounting grommets and washers), license plate and turn signals, key lock (with clip) and move all wiring out of the cutting areas. Remove the two bolts at the rear end of the stock fender (inside glove box) to allow the end to hang down for cutting.

Using a "Dremel" tool or cutting disc (this can also be done using a sharp edged knife, but is not recommended), remove the plastic shown in the photos to the above. Your subframe may be different but the cutting position is the same on all years. Be sure to take your time cutting, so that you don’t cut away any more plastic than necessary. Trim off the back portion of your glove box, but make sure to leave the sub-frame mounting tabs connected. After cutting it is a good idea to test the fitment of the undertail. If the undertail is not fitting properly you may need to check your position and cut a little more. Remember cutting less is always better!!!
3) Insert lock into undertail using stock lock mounting clip
