I removed this from a 66 or 67 Chevelle in the early 1990s. Likely about 1993. I have had it stored ever since.
It would benefit from a good cleaning and buff/shine. Photos show overall condition.
The bezel appears to be in pretty good condition. The center cap has some surface cracks in the plastic.
Please ask any questions you may have.
Another eBayer has indicated this is from a 66.
