There were hundreds if not thousands of them things hauling grain and rock in Texas in the 60's and early 70's. When gas went from 20¢ to 50¢ a gallon, those that were still in service were scrapped. They were worked hard and its been a long time since I have seen one in the shape as the one pictured. It would probably have been born with a 409, New Process 5 speed and an Eaton Electric 2 speed and straight air. The 10 hole Budd hubs were probably original, but originally it probably had 10.00x20 tires on steel wheel. The tubeless aluminum were probably added later, but they are just a bolt on with no other modification except for longer studs which is an over the counter item. The West Coast still hasn't completely gotten away from 10 hole stud piloted wheels. Other parts of the country stud piloted aluminums are sold for scrap.
