Replacement Mounting Hardware and Lid Hinge for Old Thule Alpine Roof Box


I have a 2017 chevy suburban. I am going to add the standard GM cross bars to the factory roof rack rails. I have an old Thule Alpine box, same as shown in the attached photo this photo was actually taken from your site. It has the square u-bolts that attach to the Thule square rails. Is there a Thule kit that I can buy that will allow me to attach this box to the factory cross bars? I am willing to drill holes in the box if needed. Also, the gas struts that hold the box open have failed. The Thule dual strut replacement that you had recommended to someone else part number 14933, I think will not fit because the attachement balls on the box and lid are not located such that they would line up with the attachment points on these struts. Is there another option? Are replacement struts not available from Thule or perhaps their former supplier? I am trying to avoid spending $500 to replace the box since it is in perfect condition except for the struts and the mounting issue. Thanks in advance.

To mount your older Thule Alpine Cargo Box onto the factory crossbars of the 2017 Chevrolet Suburban you can use the Replacement QM3 Hardware # TH04997. You will need to drill some new holes in the cargo box but the QM3 includes stick on hole covers for the old holes.

The correct Replacement Lid Lifter Hinge is # TH14936.
