Building a Replacement Foot for a Thule Sidearm

Expert Reply:

The washer plate, part # 853-0333-02 is used to position the front mount along the track of the Thule Sidearm, and you're right, it is missing from the question you were looking at.

To fully rebuild the assembly, the correct parts list is:

2 Washer Plates, part # 853-0333-02
2 Wing Nuts, part # 753-0783
2 Carriage Bolts, part # 915-068-054
1 Levelling Gasket, part # 853-7442
1 Metal Bracket, part # 853-5513
1 Clamp Bracket, part # 853-7441

You need to do this for both crossbars if you need to fully replace the mounting.

As mentioned in the other question, the XAdapt 2 kit, part # XADAPT2 is also an available kit to fit to most factory roof bars.
