Allen,
Before you advertise those caps, you might want to consider the following.

Regular Equipment section:
"Wheel Hub Caps, Bright Metal. Standard on all conventional Chevrolets and Corvair 500 and 700 models"
Optional Equipment section:
"Wheel covers: Vented. Dealer installed accessory or factory optional accessory (FOA 117) for all conventional Chevrolets. Crossed flags with ""Chevrolet"" above and below stand on black painted background of center of cover"

Regular Equipment section:
"Stainless Steel Hub Caps - All Models"
RPO & FOA section:

Dealer Installed section:

Engineering Specs section:
There is a photo of the disk pictured at the beginning of this thread. Under the photo is printed "Accessory Wheel Disk All Models"

By the way, I don't know much about Pontiacs, but they are my second love. I'd have as many of them in my garage as Chevys if I could afford it.
