Just bought a pair of Yakima bike carrier, but need attachment brackets to mount it onto factory roof rack. The bike carriers will work with Yakima vertical Mighty Mounts (won't work with Universal Mighty Mounts). I read in another thread that Yakima Vertical Mighty Mounts 14H is not a perfect fit for P5's factory roof rack, but nonetheless it will work. I also saw that Mazdastuff.com is selling bike rack attachment brackets (Mazda part number 0000-8L-J01) that will work with a Yakima bike carrier. Now, Is this bike rack attachment brackets from Mazda made specifically for P5 roof rack (perfect fit)? Or perhaps it is just the same exact thing as Vertical Mighty Mounts 14H? Does anyone know?
