Hi 56 stepside,

Don't know if it will help you but I can give you the order for a 1955 3200. There are 5 bars on my truck. Starting at the cab and working backwards the first two are the taller ones. Next (where the frame curves upward a bit) are two shorter ones followed by the last tall one. In between cross member number one and two and aft of number 5 there is a row of bolts that go through the wood without a cross member on the underside.
