I used them on my 10 build. I tapped the 4 holes for a #6 screw that allows me to put them on and off for fitting. When I’m done just add some locking nuts and you’re fine. Highly recommend them.
The original Vans part (pre 2007?) suffered some weld failures. The improved part (post 2007?) has, as far as I know, given good service. But it is kind of ugly.
