If that doesn't work, search by date. It was May 13. You can shortcut a page by page search by clicking my user name, selecting view posts, and it's nose align in a 9.
If you have a strong mechanical aptitude, you don't even need to look at my post to understand what's going on. The car and subframe is a stationary unit. The nose doesn't have lateral or width adjustment. It bolts in its non adjustable, stationary location, and the core/fenders are shifted until they align with the nose.
Gm had standard engineering, meaning they used the assembly process on multiple makes that also pass through multiple years. In other words, the same approach--most likely--applies to a lot of hokeyass GM noses. Now that I have found what is clearly a lost key, I could tell wether or not it applies to other vehicles by inspecting the way the nose attaches to the car.
