Rick,
I've been searching for someone myself.
One guys said he did, but never answered any emails.
One of the problems with that is, the workers pretty much only know how to put in a few parts at a certain station.
I want to meet someone in management.
They would know.
I would think that the same is done even now, so even someone working on an assembly line/management now, would know.
And if they do, they may not be allowed to talk about it.
I remember for years, you couldn't take in cameras in the plants.
Then, around 1992, Van Nuys allowed it (since they were going to close).
And of coarse, i didn't take my camera then.
When I wanted to go back, they were already closed.
Maybe meet someone at the Corvette assmebly plant right now would know.
I'm sure people go visit that plant (too far for me).
I did meet someone who was in Pontiac advertizing.
He worked on doing the big billboard ads that were all along the freeways (at least, in the Los Angeles area).
Yes, I even took some pictures of those as well.
