I agree with Tuna, I'm fairly certain the 28H parts are the Yakima part number for the Xterra factory crossbar mounts. I got a set of Horizontal Mighty Mounts from CourtesyParts.com and they do work with my 06. The Universal also work fine, but they are expensive compared to these. I opted against using the factory bars though to put on a LowRider Max kit and Yakima xbars.
Did you just use their online rack config tool or did you call Yakima? They've always been super helpful on the phone with me.
