Hey Ryan. The Thule 422XT XSPORTER's been obsolete for awhile but we do have clamps that will work with it. They are the Replacement Bed Rail Clamp for Thule Xsporter Ladder Racks item # 8523159001. For bolts that hold the c-clamps in place you will have to go to a local hardware store and source them. They measure 3/8"-16 X 3.0".

Where did you find a Thule 422XT?
