9509N x 1. The correct Larger version of the unique Clamp Nut in the XK120 boot to suit the spare wheel clamp bar for the standard thinner STEEL WHEELS; screwing onto the swinging arm (Spare Wheel Hinge) on the upper floor / shelf. Made in steel, comes in self finish, so you may paint, powdercoat (or even as some do, chrome plate it for extra bling in the boot!). This nut features the same size across flats as the disc wheel nuts so that the conveniently hung nearby wheel brace may be used to fasten it up. Original Ref. C3864
