Moving the shims will change the caster in hub assembly. Some caster is good. I have no idea how to measure that, though. I would say that as long as both sides are the same, you're good.

The other issue is the articulation of the rod end. It looks like housing of the bearing is flush and tight with the side of the upright. That's a bad thing. You could be putting undue side loads on the rod end, and cause it to fracture. But, I'v never worked on a Superformance, so I could be wrong.
