I'm looking as well...
How did it go? When you put the screws into the cup holder was there any issues there like the plastic stripping out and the screw free turning? Does it feel tight and secure after screwing it down?Okay, update...
It allows you to drill four holes in the bottom of the cup holder, which I have not done yet, but even with a tight fit, it does move around, so I will be drilling four holes to bolt it in. ...
