I'd like to replace one of my wakeboard racks on my 03 B52 with a combo rack that holds a surfboard and a wakeboard. I have looked at a lot of them on the internet, but there's not enough detail on the mounting to see whether it would bolt right on to my tower. I could just get one that mounts on the tubing (1-7/8") - but I'd rather just replace the existing to cut down on clutter. Any suggestions? My surfboard is taking a beating going in and out of the trunk.
