There's this one in the For Sale section atm:
http://myswag.org/forum/index.php?topic=23169.0To be honest, if I was in your situation, I'd be looking for a petrol 80 or GQ. Something like :

http://www.carpoint.com.au/all-cars/private/details.aspx?Cr=6&R=12376877If you're not going to be doing a lot of kms, then paying extra for the diesel isn't really worth it (IMHO). Or, given the mention of said "muscle car", buy a basic GQ for not many dollars and stick an LS2 motor in the front. Heaps of conversion kits to do that these days, and the fuel economy is pretty good. Ebay is full of gear for GQ's, and everyone knows how to work on them.
Personally, I'd stay away from the 60 just because it's so hard to find a good one, and the leaf springs. Yeah, they can be made to work, but starting with coils is going to give you a much better ride and a much easier time. Again, if the muscle car thing plays out into the rest of your life, a 60 with a big petrol v8 wouldn't be bad either. My concern would be that, having other nice new vehicles, hopping into an old 60 for a month's touring holiday with no AC and old headlights is going to be pretty jarring.
If it were me, I'd buy the blue GQ above, spend another $3k on lockers, and the remaining $2k on bits and bobs - cargo barrier, brake controller, new fluids and filters, seat covers, maybe second-hand set of drawers, etc. All the little bits and pieces to bring it up to scratch as a comfortable tough truck.
Good luck - I'm sure you'll get heaps of other good options!
Cheers!
