I noticed that the Duetto hubcaps are still avaliable. The small circle hub was used on early Duettos, but they came on the Giulia GT Veloce and saloon too, didn't they? Nice to learn that parts are still on the market.
I bought a set of four of the reproduction hubcaps. They look very nice and the only difference I can see from my (banged up) originals is that the plastic ring on the repro's is guled in place where the originals have four posts with clips on the inside.
