How much do you want to do? Do you want to do a frame off restoration? If the body has rust on the floor boards and frame needs to be fixed or replaced, do you have the space, know how, time, and money to fix it? If you have a welder and are good with it and want to fix the parts you can and have the time and space, I'd say do it.
I do not have any of those things, so I would be more interested in selling it to someone on here that would love to get their hands on a stock YJ that hasn't had someone botch the suspension, and look for a rust free platform that I can upgrade vs. restoring.
