Rear end geometry 67-72 questions

[VA72C10]

I appreciate that info and that will assist in the final setup once I determine ride height.

My question really relates to the physical characteristic of the rear end....it is 1" longer from the yoke to the backing plate behind the axle on the driver's side (I think) than the passenger. So since the saddles for the trailing arm are the exact same distance from the yoke, when you center the yoke, it puts the wheels off center in relation to the frame. Once you center the wheels, you end up with one U-bolt under your frame, and one next to it. Just making sure that's normal. Both rears I have (72 5 bolt and 70 6 bolt) measure the same so I assume it is...just trying to determine the factory logic behind it because it wasted 2 hours of my time trying to figure out why I couldn't center both the yoke and wheels
