I noticed that Kevin and don't know what to make of it. It's not definitive for the 14x6 chrome wheels, as that picture is of the 15x7 which had a black center. Still wish I knew what Buick Spec 345 was!!

If I accept that the drum color behind that wheel is correct, then it appears to be a light gray or silver. Very helpful that it's a black and white picture...
I have a bit of time to decide, so I'll keep pondering....
A good weekend to all!
