Im replacing 1960s taps with modern ones and have realised that the shank on the new taps is a lot shorter than the originals so the water pipes now don't connect up. I could put flexible hoses in (not sure how to do that) or I could find new taps with longer shanks, trouble is all modern taps seem to have 50mm shanks. Does anyone know where I can get taps with longer shanks (70mm)?
