I think it was actually an LJ (TJ Unlimited) frame that they used and that the wheelbase worked out quite well. I think the suspension set up of a LJ and the vintage of a Willys is quite appealing. It also has ARB air lockers in both axles. Talk about a sleeper! Cruise down the highway at 75, wheel on the weekends.Wow, I had no idea that was a TJ under there. That is pretty cool! I was wondering what "SOAZ" meant by that. I wouldn't have guessed the wheelbase would be the same.
