For over a year I have driven an 1984 nissan 720 4wd with a z24 motor. It had 42k when I bought it and just last week hit 60k. It is excellant in all respects but one. The frame is eaten with rust, and were it not for my welder cousin and numerous angle iron bandaids it would have fallen apart by now. My question is how broad a spectrum of nissan vehicles would accept the z24 motor, which is carbeurrated by the way. The newer the better as I would like to find a good solid body.
