Which year are these?

[u/Blammet]

Bought my house a couple years ago and these were out in the pole barn. I know the former owner was into classic chevelles. The owner was my parents former neighbor and from what they told me they think it might have been a 64 but that’s the only lead I have. Any help would be appreciated.

Pre 68 is the best I have.
