FWIW, I only used Points A & B to get all 4 wheels off the ground.
I lifted one side first at Point A. Put bricks/blocks under Point B. Left original jack at Point A.
jack to raise other side of car at Point A. And then put same brick/block supports under Point B.
Car was rock solid, no wobbles, etc...
Pics show it better. Same set-up for each side of the car.
