I've got an HJ60 cruiser here that a customer has bought solely for its engine - 2H - for me to put into his bus as he cooked the last one

Being a nissan lad at heart I've never really looked into the dark side of toyota

What I'm thinking of doing is buying the rest off him, and selling it out as parts, but just want to make sure I'm not going to be stuck with the lot because its worthless crap, so can I have some genuine answers please on the value on the following, could be worth something, could be not worth my hassle and time. I figure most if not all of you will know whether this stuff is worth buying and what you would accept if you were selling it yourself.
- Body - rusty (worthless I know), however all windows are there, etc.. seats are a bit on the 'have been sat in a lot' side
- Gearbox & Transfer Case (no crunches aparently, in saying that I havn't driven the vehicle myself - and its got no engine so hard to flintstone and find out)
- Diffs. The front one looks to be strengthened underneath, aftermarket, and not a bad job done. Its got manual locking hubs. Ratios unknown at this stage, if it makes a huge difference on price do tell.
- Tyres - 1 is wofable, maybe 2, the other 2 are a certain no.
Chassis looks to be ok, so possibility of selling the whole shebang and heaving it onto someones trolley and goneburger is certainly there too.
What I don't want to do is put bits and pieces on trademe and get the usual - bro got a wing mirror nut? Don't really have the time for that crap.
If its all junk and realistically going to be worth more to me to get my apprentice to strip it down and head for the scrappy, also handy to know.
Cheers guys. Honesty is greatly appreciated.
