FWIW - I bought a used 4VBW from a cadillac dealer that was missing the steering wheel numbered badge / data plate (had the two holes as pictured in DCTFUL-V's post above). As part of the sale, the dealer wrote up a ticket of deliverables including a replacement steering wheel numbered badge, the blackwing badge for the decklid, etc.
4 months later they called me to say that while those steering wheel badges can be ordered, they are only in production occasionally and they need to provide the original plate number including the number in series - which they have no way of knowing and apparently GM also has no record of. They said they'd keep working on it and get back to me.
In the mean time I noticed that the V wheel for sale on aliexpress has a generic V badge:
I asked the seller if I could order just that badge as it would be better than those two holes in the CF:
The answer was no
To my surprise a package showed up today from the selling dealer with a made-in-China steering wheel V badge just like the one at aliexpress, but with a GM part number.
I'll take it.
GM part number 84873504 - can find it on many of the GM parts sites for the low low price of $50 (special order of course)
