I believe I stumbled upon a '68 or '69 Belvedere...

There was no VIN on the top side of the dash, nor any evidence the VIN was ever on the dash.
I assumed it was on the door jam, but the DS door is damaged and can't open...Maybe I looked in the wrong place?
The body color under the trim tag was/is Green. As a matter of fact, the whole engine bay is still the original Green.
