Lower Radiator hose for Slant 6 in a 68 Valiant

I've tried several local parts stores and online purchases, but every one of them I had, I had to take back for a refund. Does anyone know the right part number for the lower Radiator hose that fits the slant 6 in a 68 valiant? The ones they keep selling me are either not molded to fit it or they are too short!!!
