Bad day on the assembly line?

In 86 a friend bought a new 5th ave, I followed him after he stopped by the shop to show it to me and noticed it was dog tracking. So he brought it in the shop and what I found was the spring hanger and rocker panel on the rt side was 5/8" forward. Chryslers fix was to add a stack of spacers between the spring hanger and the mount and call it good. Quality job one.
