Nope. That's a pretty famous build done by Boyd C. for Eddie Van Halen back in '93.
There's a bunch I like about the truck, & some things I don't. But considering it was built when it was, it was pretty cool in it's day.
That C4 rear swap has been done plenty of times since.
There's a guy on F/B that's done so many he says he can do the swap in a weekend.
In the door Firday night, rolling out, done, Sunday afternoon.
I had pix of one done, without the box on. Lost when an old computer crashed. Can't seem to find them posted up anywhere.
