Nope.
Aftermarket parts would be dealer or owner installed. We do "one off" builds on the assembly line for engineering and manufacturing testing but not for a customer, and as planned major milestones in the development process (not spontaneous events - there is no room for spontaneity on the assembly line).
For an '87 model year truck: Depending on what plant, and what shift - I would have seen it get built
or probably would have heard about it ahead of time.
I'd be interested to see whatever paperwork he thinks he has: build sheet, window sticker, dealer paperwork, etc. One good thing is that the invoice for this truck would be available through the GM Heritage Center archive and would show this content and pricing if it was done as he says.
Bottom line is that even if what he says is true if the paperwork doesn't reflect it then the historical community cannot "legitimize" it. I know this first hand from my experiences with Dad's '65 GTO.
