it is a 70 240z and it is the actual ball joint and steering knuckle. so the old one had to be put back in for now. there is a 70 in the junk yard but if it, the knuckle, is from another car a may put in the correct joint for that steering knuckle.
When finishing up the rebuild of the front end i discovered that the ball joint on the right side is smaller than the left side! Does anyone know where this might have come from? everything else fits well and looks right. Thanks, boyd8
