Description
1 new Cadillac original piston with piston bolt in Standard dimension, for a cylinder diameter of 4" = 101.60mm. The piston that was manufactured by Cadillac approx: 70 years ago has not been mounted in any engine, but it has probably been stored in a bad environment and got an oxidized surface. The oxidized surface is only a discoloration of the casting and does not affect the function or change the dimensions in any way. This is a spare part that we call NOS. It stands for New Old Stock, i.e. spare parts that were manufactured when the car was new and were just sitting on the shelf. So not newly manufactured parts, hence New Old. Wash the piston with degreaser before assembly to remove any loose oxidation. The casting number inside the piston is 1463227
