Here is what Dallas of Stinkyfab had to say...
Everything I have seen and heard tells me that they will work, though I have not actually tested them on a VX yet. If you can take a couple quick measurements from your truck and email em to me I can tell you for sure. Either that or maybe one of the SoCal VX guys could stop by for a test fitting. If they are different, and I can get a VX over here for a day I will make up a Jig for them as well.

I will get the measurements for him tomorrow!
