Replacement Hinge/Strut for Thule Evolution Cargo Box

I have an older Thule Evolutuion roof box. I am not sure of the model number. The interior dimensions are 31 wide by 73 inches long. One of the hinges has worn out and wont stay attached to the mount. I need a new hinge... can you help? I have attached pictures of the hinge and dimensions open and closed. thanks in advance for your help,
