The difference was the width and number of boards.
The 58 amd 59 fleetsides are unique. I can make my own wood, and probably will. I was just hoping to find a reasonably priced kit so I can spend my time on bits and pieces that I enjoy more.
Based on the holes in the crossbars and the other 58/59s I have seen (including my 59), I am very confident that what I currently have is original.
