SS rear bumper

[MechMan]

Is there any way to tell if this bumper is the pre 87 style?

Yes, it is pre 87'

As noted it being a pre '87 rear bumper cover, '83 to '86 cars used the black trim ('81 to '86 non SS or LS used chrome & has extra lower side trim) as shown with arrows.

Ok. Thank you very much for the help and knowledge.
