The photo is not actually of my particular truck but just a photo to show what I'm up against, my truck box is currently apart so I cant show it. My truck is a 1946 GMC model 9434 1 ton express box pickup, same as the photo. This is a factory setup, from what I do know the 1 tons only had this setup 1/2 & 3/4 did not, seems that the 41-46 years did this, not sure of the AD styles.
