That's some spiffy tech, but there's a lot more to getting that right than that guy lets on. He's a professional fabricator and damned good at his job, whereas I'm a driveway monkey with an anglegrinder. I could probably do that, but I'd ruin several axles in the process and probably spend more than it'd cost to just order the danged RuffStuff in the first place.
I'm gonna watch for him to put out a kit though.
