Judging on how the axles/birfields look (if they’re trashed you might be SOL), I’d strip the axles, put new bearings and races in them, possibly new rotors, grease the knuckles up to prevent rust, fill them with fluid and roll them around in the yard (to prevent rust) until someone bought them, and make about $1,000-$1,2000 profit, possibly more with wheels. Pull the trans, t-case, and motor and sell them as a package, with upfront honesty of what condition the truck was in, for about $300-$600, start parting out small things like headlights and seats for nickels and dimes just to recoup as much money as possible, and like I mentioned before scrap the rest to try and break even. You could spend $10k-$15k on a good running 80 series with some records and receipts behind it and be loads of time and money ahead of where you’re starting with this thing. I know this is my second post saying to run from this thing, but you really do need to treat it like the plague. These aren’t like Jeeps, Tacoma’s, or 90s model chevys, parts are hanging from trees in everyone’s back yard, and when/if you find parts in good shape from knowledgeable people they aren’t going to part with them easily because they know what they have. I know you hate to hear the news, but it’s not the end of the world either. Depending on your patience, research, and some elbow grease you could possibly make a little profit if your lucky. If all else fails you could scrap the truck whole for about $1,300-$1,800 realistically, or possibly sell it for parts to someone on here for $2,000. BUT, without some work on your end I’m afraid you might be stuck with a loss unfortunately. On the other hand, it looks like your acquired a pretty nice Jeep. Possibly one of the better ones they’ve made in the past 25 years.
