Since were on the topic of line workers & what happened back then I have a story. Mine was a V-8 LTD with the V-8 sticker already on the AC box that says Carbed with a diagram. (still have it) The VP of GM Canada Nick Hall pulled the car for his brother-in-law off the line & told them stick in a 3.8 Turbo, 2004r, 3.42 rear etc. etc. This was a loaded LTD with what should have had power seats but they didnt do that with the Moonroof option. (I added them to both sides later) The badges were 3.8 Turbo hood, the Red "T" on the front fenders, Grand National on the Pass trunk & 3.8 Turbo deivers trunk & no dealer name plate.
Also, he did NOT want a hood emblem so they used a GN header panel! Only LTD I know of thats like that with no ornament! I have asked everyone about it. Eric, I'm sure you can verify the hood ornament on the LTD model.
Just shows with the pull of the VP of GM how he got what he wanted for his brother in law. I got the car a few moths later in May of 88.
PS: My SPID label is correct but my Serial # is sorta weird.
Back to topic, I doubt the line would put on a chrome grill for anyone other than maybe the President or VP & especially on a GN. Wouldnt happen without someone catching that. The dealer accident sounds more likely to me?
