Just to let you know, it is not the same as pictured in your inital message.. it does not have the swivel ends that clamp on the wakeboards. It is the straight one before the swivel board presure pads came out. I hope that makes sense to you.
My rack configuration doesn't use a swivel. The two rack (finger) are actually rigid mounted on my tower. I have an '04 x-30. Nonetheless, I'm interested in purchasing one of your "finger" if it is for sale.
