Referring to #7 on the street, for most people, I would vote for the knee as a target for the kick along with a #1 block, open or closed, as a guard. Most men can take much more in the ribs, than they can the knee at that angle. But, if it must be ribs, then the floating, or short ribs would be the target. Any higher will not have much affect on a male, you're up into the muscle. For most, my teachings are step aside, kick the knee and run for it. By the time the attacker figures out whether or not he is hurt, you'll probably be 30 to 40 yards away, most likely safe unless they have a gun. Just my opinion.
Also, this technique done in a slightly more advanced way, can take advantage of a left step outward using either a #1 open hand block and grab the wrist or a #1 iron fortress with dragon trap and hold them steady for the kick, again either taking the knee out or the ribs, both are quite effective.
