Bought this 91 YJ in November 2011 for 3600$. It was rusted, and the SOA was scary, but the interior and hardtop were really nice. I quickly sold the hard top for 1000$ and tore it apart to rebuild it.
And that is how it currently sits. It is now running and driving for the first time in over a year. It is not register, inspected, or insured yet but i have been driving it around the neighborhood and gotten it up to 60mph with no vibes or issues. Well except the front tires will rub the leaf springs at full lock but that is not surprising.
And the pictures are over the last 2 years and are roughly in order but not exactly. I am now invested in this jeep about 5,000$ total counting the initial purchase and subtracting the sale of the hard top and sale of the wheels/tires.
Many hours were spent on jeepforum and craigslist while building this jeep. Thanks for all the help YJ tech section!
