Thanks - so that would be all 455HOs, correct? Any idea what 487352 is used for?

But why they would not use a different 'pick' letters I don't know? (PL)

I thought it might be Unitized, too, but the example car doesn't have Unitized ignition. Then maybe I thought California-only but both decals say they cover California emissions at the bottom. Did they change the tune up specs some where throughout the run? If that's the case, it could explain why the decals have the same pick code.
