I agree with GTSteve, when I did my suspension initially I was going to jack the car up all the way around and set it on four jackstands. After jacking up the front I decided to just do the front, then do the rear. For the front I placed the jackstands just behind the swaybar on a solid area, see photo:
Sorry no picture of the rear but I placed the jackstands on the frame on each side at the location where the tie down brackets where located. If you have a set of tall jackstands use them on the rear, I had to set mine at their highest limit, did not feel comfortable with it, wish I had some taller jackstand.
