Jeep JK-8 Independence pickup conversion package
When I was a kid, one of my favorite uncles had a late-model J-Series pickup and it was one of my favorite vehicles. It still is.
While the JK-8 conversion package, based on the current Wrangler Unlimited, isn't exactly a throwback to the J-Series, it does share some of the same spirit. It's not cheap or easy to install--the package starts at $5,499 and will involve many hours of labor to install at your local dealer--but it's well worth it.
