It's a bit before my time. Unfortunately, while I had a lot of relatives who would know, they're all dead.

I do know that back then, especially at Cadillac, you could do a lot of custom ordering and I wouldn't put it past being a factory option or even a dealer add-on of factory parts. I've personally never seen the chrome spears on a CDV or 62 but it doesn't mean they weren't built that way. Have seen them on Eldos but they have totally different side trim.

Was definitely a cool time to be a car buyer.
