But I'm looking to see if anyone has pictures of the lift points for a '73 S30 (assuming its different from year to year), as well as the points to place the jack stands.

I have a bunch of stuff that I need to get done on my new Z (oil change, find a leak, fix a dented rim ) but I don't know where to lift from. Thanks for the help

Take the middle of the front axle and than put the stands right and left to this.

At the rear lift at the end of the diff. Be careful, put wood or - better - thick rubber between the diff and the lifter. Work careful and look that the lift is vertical, than put the stand under the rear lifting points as descipt in your manual (use rubber between lift and lifting point). That's how I work when in a hurry.

Year to year should not make a difference. This question was just asked recently. A simple search (lift points) turned this up.

Haynes, Clymers, Factory Service Manual.

All have pictures of the lift points and jack stand placement. Clymers and Factory Service Manual have better pictures.
