Over the week, I had a '58 Chevy fleetside bed dropped off for some rust repair. The outside of he bed is spotless. I am surprised how well of shape it is in. The inside, however is a different story....especially all of the sub-structure. The more I poked and prodded, the more rust I found.
After getting the bed unbolted, I chose the worst side and began dis-assembly. The main rear upright was completely gone on the inside. The only way of getting to it is by drilling the spot welds and removing the entire structure.
Not much left...but we'll fix that....
