Smittybilt HDS roof rack mounts used to mount the Prinsu roof rack. I just finished up and I am SUPER happy with these mounts over the original junk Prinsu mounts. I had to drill holes in the rack side plates to get the Smittybilt mounts to fit but what a difference they make. I haven’t seen anyone else do this but I’m sure it’s been done. If anyone has questions on how I did it let me know. It’s super easy
