This bracket kit and battery tie down are designed specifically for the 85-89 Toyota MR2 MK1 SC. This bracket will eliminate the shorting  from the positive battery pole being so close to the OEM metal tie down.  It was designed to replace the metal OEM part and is made with PVC to ensure OEM improvement in performance. The listing includes the gray bracket in the pictures and nothing else. It is a direct swap with the OEM and requires absolutely no modification to anything.  Just remove the rusted OEM and swap it with this.
