Checking the OKP Parts manuals, it seems that the 105.02.01.510.00 was OEM on '64-'65 Giulia Spider Veloces, and a number of Giulia Sprint GTs, GTCs, Giulia Sprint GT Veloces. Not sure about dual carb 1600 Supers.
I missed a number of them for sale here on the BB before I knew I needed one. I had one coming from SA, but the shipping cost was outrageous. It doesn't have to be Pebble Beach quality, as I have plans to refinish it.
