Yeah: 63= split window, fake vents on the hood
Its a 64 or 65 with that view from the back as 66 has not vent on the rear pillar.
Show us a side view and I'm going to tell you which year it is.
If you want to know by yourself I'm gonna tell you the differences:
1963: you already know except: 2 horizontals vents on rear pillar
1964: no fake vents on the hood, but have place to put them, the vent on the pillar have changed and are made of little bars (look like louvers)
1965: New Sides vents on the fender design (3 Vertical bars)
1966: No vent at all on the rear pillar
and yeah its harder to tell the difference between a 66 and 65 convertible
but new square mesh cast grill, and Corvette script on the hood.
