 
          Over the life of this design, a number of variations were pro-
        
        
          duced, resulting in changes such as the length of the side sill
        
        
          notch at the side ladders, the number of welded side panels, the
        
        
          number of running board supports and the position of the brake
        
        
          reservoir.
