I hope this doesn't seem harsh or unkind, but I reckon you need to take a step back and actually work out what you want, and, take some time to research the many and various iterations of the #J7# series before you go any further.
The first cruiser I went to look at was a HJ47 that the seller told me was in excellent condition, no rust etc etc and I was on the verge of sending my life savings (I was 16 at the time) to this bloke without even looking at the truck.
I decided that I should go and look at it before buying, and when I turned up, the thing was his fishing truck, had reasonably advanced surface rust all over the chassis and starting in the floorpans, firewall and so-on. There was bog in the body in the typical 40 series rust spots, touched up with a very poorly matched paint. The knuckles leaked enough to coat the inside of the front wheels and tyres with oil, he couldn't tell me exactly the last time it was serviced, steering gear was on the way to being unservicable...you get the gist.
My take on the moral of the story is, don't let your want for a Land Cruiser take over your senses. I was young, knew I wanted a HJ47 and had some idea what a good one looked like, but not much else than that. So, after this incident I decided I should go home and work out the ins and outs of what I was looking at, so next time, it was a more educated decision.
Hopefully this is of relevance
