Block off plate for removing the BCDD at the base of the throttle body on Datsun 280Z. Can be used when running an aftermarket fuel injection system where the BCDD is not rquired. Once the BCDD valve is removed there will be three screw holes in the throttle body that the plate mounts to. Includes aluminum plate with screws. We recommend lite RTV silicone in place of a gasket to seal the plate.
