Hi, we’ve changed to a Vauxhall Zafira, and are going utilise our old Thule roofrack, but can’t figure out which footpack to buy. the Zafira is 2013, with flush roof bars. These bars have 3 sets of two holes. I bought the kit 4025. Although, this doesn’t seem quite right, as it doesn’t have pins to fit into the aforementioned holes. What kit has anyone else used? Thanks.
