Probably aftermarket, but not the cl***ic Hollywood hubcaps that we sometimes see with a single bar ... Have you a idea? and where buy them?
Yes it looks like that's what they are. I've had a set of 14 inch and 15 inch. They're OK if that's the look you're after. A lot of options out there. These are cheap enough to mess with the look of your wheels to see what works, or not !!
these are not the ones! it would be too easy.. those in my photo are a little deeper Ideal would be to find the owner... if you know him..
