You can drop 37 pounds from your Mustang by installing our lightweight Rear Seat Delete Kit. Our kits replace the upper headrest also, to remove as much weight as possible. The lower panels are 3/16" ABS Plastic, and a 1/8" molded plastic back panel. It provides a deep hidden storage compartment and increases cargo space in the interior as well. Lower panels are removeable on both kits! The plastic will not break or crack under pressure. Works great for mounting nitrous bottles, stereo components, or for transporting luggage or wheels/tires. Detailed instructions included. We use factory bolt holes for mounting. Black carpet only.
