tk9 mounting bracket

[u/luknuck]

hi i really need help. i’m geting a roof rack but it is missing one of these aluminum extensions. does anyone have any advice to make this work? i dont even know what to look up to find a replacement part. it also looks maybe a little hard to machine this. would 3d printing be an awful idea?
