I need to correct myself.
I just happen to put my car up on the lift tonight and walked under the car. I am rotating and checking the balance of my tires while replacing rubbers on the anti-roll bar.

I found out that a person cannot see that angled edge underneath from the front of the tire. That's because of the pressed steel lips of the control arm shroud the ball joint arm.

I got what I was thinking backwards from looking at only the one ball joint from out of the box that was a lefty. I tried imagining them on the car from it setting on the bench. I hope I got the numbers right though.

You are right the pivot /ball is angled forward in relation to the center of the control arm on the power steering cars. The angled edge of the bracket, I spoke of, is facing to the rear of the car.

Sorry about that!
How did you come out on the rubber boot spacing below the strut mounting plate?
