Did anyone ever get back to you and have you installed your rod rack yet? I'm looking to do the same at the moment and found this old post of yours wihout any replies?
I phoned Beekman canopies recently and for a set of rod racks only was like R1343 excluding fitment. Then if you actually choose the other alternative ie roof racks at R645 for the set as well as rod holders that attached to racks at R125 a set you might as well go for that and install 2 sets. The fitting of it they can do as well where they charge per hour.
