My long box (59 Apache) model 32 has the factory SM420. A little different than the short box 31 model as the long box has a two piece drive shaft with a carrier bearing. My other 59 Apache which is a model 31 was butchered and hot rodded many years ago by a previous owner so it would be of no help to take any pictures.
