Couple questions on 1987 gmc v3500

[White halftrack]

Hello everyone. I have a few questions on my truck. The front bumper has fog lights in it but the bumper is beat up. I can’t seem to find bumpers for that year with fog light holes. Is it not original?

Front grill is the newer style flat lights side by side with driving lights below. When did they start these? The gmc”s like this seem to be later and was curious if it was switched.

What was original wheel covers for Duallies? Were they just painted or was there chrome hubcaps? Ye9 package

Did they still use hood ornaments on this year?

Thanks in advance.
