Just need a confirmation and if I'm lucky maybe someone has a pic

I know that the bumper PN changes in 1993, and my understanding is that essentially the only change is in the bumper strip wrapping all the way around the bumper on the later cars - pre-1993 ones also having the PPO finish/matte black. Is this correct? I'm assuming the wrap changed because of the cladding that was added later?

Is the mounting system and hardware identical through the years?
Does anyone have a pic of an early bumper on a later car?
