Rare OEM running boards

So my old neighbor who just purchased a 2003 ford escape XLT has these sporty silver runningboards. They are a 1.5-2 inch silver tube that is more looks than function. I have this one picture that I found. I have seen these before but cant find them anywhere. Im trying to replace my running boards because I think they are rusting from the inside out. They still look good from the viewable side, but they are rusting up on the bottom in a few small spots. So I would like to track these down if possible. Does anyone know the Ford part number for these?
