I have an 08 supra with the button on the bottom of the wakeboard rack to make it swivel. I called roswell today and they have none of the three pin nuckle replacements for our towers. I looked at the pick of the si swivel on roswells site and it doesn't look to difficult to drill three holes in the top of the nuckle. Have any of you guys done this mod yet and if so any advice. Thanks Gene
