So, my son is 12 1/2, and loves old trucks. He's decided he wants a Willys pickup when he turns 16, and I'm thinking about a dad/son project for the next 3 years. But, I honestly don't know a lot about Willys pickups, other than they share some of the early CJ mechanicals. My idea would be a resto/mod type vehicle...keep it stock looking, but with a more modern drivetrain and better steering & braking. Any thoughts? Things to avoid? Are certain years better than others?
