SET OF 4 GROMMETS (Sensors not included) These grommets are specifically manufactured for reverse sensors to mount securely onto the rear of tray bodies when converting from a tub body to a tray body. Designed for replacing factory parking sensors. These grommets have been tested with Toyota Hilux N80. They may work with other makes/models but not tested specifically on others. Hole required to fit grommet = 28mm Grommet inside hole for sensor = 22mm Note: Please do your own test fitting before drilling holes, vehicles dont share the same sensors, so we provide a recommendation but some vehicles may differ.
