Good to know that they are interchangeable, not that I am surprised. My Sport is an '03, so I have the standard flat running boards. There is a pretty clean set of the tubular ones that just popped up for sale near me and I had the same thought as the OP when I saw them last night.
Are these tubular steps prone to severe rust like the Ford ones I've dealt with in the past? 97-03ish Ford Rangers and Explorers that have been in the family always had extreme rust spots, but that may have just been a Ford thing, ha ha. Anybody here have any issues like that on these?
