The springs in my letter box flap are all broken. I have checked ebay and googled but no joy as all are too large. There appear to be 2 springs per flap, that is me assuming they havent just halved in two. The pieces I have are about 10 mm long and an outside diameter of 3mm. They dont fit on a rail but inside a groove so the external diameter is more important than the inside diameter. I assume where broken off there would be 2 straight lugs. To me the springs appear quite small but cant see how I could incorporate anything larger (diameter)
Any suggestions for a source or indeed a DIY solution.
