YOU ARE BUYING 4 SEAT PASS THROUGH BEZEL KITS, EACH KIT DOES 1 SEAT. THESE ARE SO YOU CAN RUN A 4 OR 5 POINT HARNESS THROUGH THEM TO KEEP THEM IN PLACE, OTHERWISE THEY FALL OFF THE SEAT.
INSTRUCTIONS ARE PROVIDED UPON REQUEST ALTHOUGH THEY ARE EASILY FOUND ONLINE AND THERE ARE TONS OF YOUTUBE VIDEOS. THIS DOES REQUIRE CUTTING YOUR SEATS BUT IT IS NOT AS HARD AS IT SEEMS AND BECAUSE OF THE LIP ON THE BEZEL, IT DOES NOT HAVE TO BE PERFECT.
