By sport tubes, I think he means the ones that are oval and have no blac step plate on them. Correct?
I got a guy a pair of these from a tacoma and he got them to fit, by making his own brackets though... There isn't an application for these "sport" tubes or the 4Runner...
I do have the other signature and platinunm serues bars, which are the standard lookig tube steps with black step pads, etc.
