The Thule Hullavator Pro Kayak Carrier part # TH898 will not require any adapters in order to mount on the Yakima OverHaul HD Adjustable Truck Bed Ladder Rack part # Y01151-59. In order to secure the Thule Hullavator to the Yakima OverHaul HD Crossbars you will also need the Thule One-Key Lock Cylinders part # TH450400. There are two lock core slots on each Hullavator.
