The 1957-1960 F350 to F600 trucks supposedly had a running board option available. Does anyone know about this? The running boards were like what was on the larger rigs (F700 +) but theoretically had unique brackets. I have a source that claims what he has for sale is such a set. Hopefully someone either has a dealer book or some literature that shows this stuff. It would be great to add the boards to my F600, but only if they really existed as an option.

Thanks in advance for any advice or help.
