An oldie

The earliest Stingray, in 1963, was the only model-year having a split rear window. Hard to tell for sure, here, but this looks not to have the split up the middle... The upper chrome strip looks uninterrupted.
It's a '67, note the backup light above the license plate.
Very nice looking car... It occurs to me that at this time flat two-piece front windshields were on the way out. And flat-head motors too! GM was mostly OHV motors at this time, and didn't they have curved front glass too?
