The kick panels are the fiberboard panels located next to your feet toward the sides of the car. The kick panel is held in using the Hood Release Cable Bracket (2 bolts) and special plastic rivets which are not currently available (they are not the same as the interior rivets), so take care when removing your originals.
The image above shows all of the holes punched out on these panels. These are ready to punch out; however, they will not be punched out when you receive them. You only need to punch out the holes you need for each side.
