Made by a stereo shop in Florida (as seen on youtube) for $150 These pieces will move your seat forward 2 full inches leaving plenty of leg room while giving you more room behind the seat. Store tools, survival gear or most important more room for woofers. I had these installed and seat is just as stable as stock. I need more room so I'm having different ones made. 1 has a couple extra holes but no worries, still works fine. $100 shipped conus, buyer responsible for any other costs
