Yes and thanks. It was a b*tch to make sure it was aligned just right. I still got it off a bit, but it will work. So far there is no leaks, but time will tell.
Installed the Yakima Skyline Rack system on my Diamondback 270 Cover. Getting it ready for carrying bikes and Yakima Skybox. Future plan is to get the Yakima Overhead HD towers so I can also carry my kayak or Yakima Skypeak.
