The one pictured on the left I believe to be upside down This bracket started life in Australia as a Cortina XLE headlight mount, When Ford in Australia needed lights for the Aussie RS, they cut the Cortina bracket in half and drilled new mounting holes, this separated the lights to allow them to fit the nose cone. If you ever get the chance to see an import RS with the nose off they are nothing alike. Hope this helps as if you can't track down an RS one then you can also look for a Cortina bracket and cut it in half.
