Is a good question but I imagine the tubes are welded to the wing section. Or else the thing would allow the tubes to slide, except that tension rod would be only thing preventing lateral motion. I think it’s welded as one piece. For me cutting out tubes only and welding back with the sheet metal portion left in situ, then re brazing old brackets, not worth it. Am thinking out with the bad, in with the new, as much work as it’s going to be. If I wanted maintenance free I’d have bought a new Subaru.
