Sorry to hear about your jeep, at least no-one was seriously hurt.
Time to part it out, if you don't get the settlement you want, and hopefully, you'll get enough to get back into another ZJ, maybe even a V-8.
Sometimes, what seems like a crappy situation, can actually be a blessing in the long run. When my 95 Laredo got totalled, the settlement I got was enough to get me into a 97 Limited, so 2 years newer, and a model up. Hopefully you can do something similar.
