The K323 uses rivets which are only designed for attaching to sheet metal, not fiberglass. The best option would be to install Yakima tracks with capnut hardware and use fit kit K450 to attach the crossbars to the track. You'll need to make sure the crossbars can be adjusted to the width you need them to be. Feel free to contact us with any other questions.
