68 dart exterior moulding help

Hi , I have an australian valiant , same as a 68/9 dart. I need the curved section of moulding thats about 2 inches long in roughly the shape of a letter C. It goes on the end of the stainless moulding that runs along the top of the door and then curves up the C pillar.
Does anyone know if there is a reproduction of this mould and if so , where its available
cheers Ben
