Hy 53 green 1-ton, I am operating under the assumption that you are looking for rear brake return springs for your 1953 3800. Some of the newer 40 series trucks use 14" X 2 1/2" front brakes, the return springs for those are Napa p/n UP80163, see if your local Napa can get you the length specifications, or springs for comparison, hope that helps.
