Steel adapter kit for early Mustang power-steering boxes and similar systems using 1/2-20 and 5/8-18 inverted-flare ports. Made in the USA and zinc-plated, each adapter converts the factory flare seat to a -6 AN outlet for custom hose routing. Kit includes crush washers and Teflon O-rings for sealing against a flat, machined surface, and the sealing components can be removed when used with ports that contain internal inverted-flare cones.
