Hello ND1956Chevy6400,
Welcome to you! That's a nice truck, it looks a lot like my '56 6500, even the color. There are a lot of knowledgeable people here. I have many of the old books on these trucks and if I can help just feel free to ask. Here is a pic of my truck "Spot". It has a 261 6cyl and two speed vacuum shift rear axle. Hope you enjoy that truck for many years to come.
David
