turns out there are at least three types of roof rack for the 240 wagon. They all look very similar save for chrome or black though the bolt holes are different into the roof.
I have two sets of roof racks that are different to the ones I am looking to replace.
Google images should have plenty of pics of 240 wagon roof racks. I like them, some do not.
They would not carry a lot of load, I use Thule gutter mount racks for anything that goes on the roof.
