It would personally kill me to sell a vehicle of mine that I had for any period of time for parts. As for advise, its would be a lot more dramatic of an experience trying to part it out that to just out right sell it. Besides the tearing apart for the desireables, and the accumulated mess from that, you have a hull that will end up needing towed away. Let alone watching this happen to something I'm sure you grew to appreciate. Sir, what shape is the body in? Floorboards solid? Rear fenders? FSJ folks expect things like the sunroof and rear window to go out. Its pretty common on these beasts of burden that we love. That won't stop someone from buying it. And with BJ's Offroad and others selling a wide variety of parts, those gremlins can be remedied. If it were me I would put it on the For Sale board on this forum, list it on your local craigslist, and sell it with the dignity these vehicles deserve.
Just my two cents.
