A Body Rack and Pinion Converison

I'm still trying to sort out the steering geometry puzzle, akerman angle in particular.
In earlier posts it was stated that this angle is incoperated via the attaching arm on the lower ball joint, and the differences between the left and right hand arms.
I ask you to look at eaby item number 380161464370. Those appear to be mirror image alike. I know the later model arms differ from one another. I guess my question might be when was the akerman angle incorperated and why.
My junior works at a local Quick Lube. I've asked him to look for differences in left and right parts, their lengths, etc., on the many R&P cars he services daily.
He says he is not seeing major differences left to right in these components.

If you draw an imaginary line from the balljoint through the outer tie rod centers ,the meeting point from both sides would intersect at the rear axle center point for perfect akerman angle. That is what causes the inside wheel to turn more in a turn. In a front steer application the tie rod needs to be outside of the balljoint so when you would draw an imaginary line from the front tie rod center to the lower ball joint center it would intersect to the rear
Here is link to a good explaination of akerman
