These stainless steel plates are designed to repair damaged side tab attachment holes for the OEM Mazda NB MX5 (1998-2005) front bumper.
To install, simply drill out the existing rivets on the bumper tab tabs and rivet it back with the repair plates on top or the bottom (The repair plates will work either way). If rivet tools are not accessible, Plastic Jb weld for example is a suitable adhesive (not included).
