In the cars defense...
The hood is a 67, 68s had holes for the hood mounted turn lights.
You can see the vin tag on the a pilar
The car has the 67 only vent window locks.
Radio with knobs.
When the 68s came out my grandfather thought about adding the round marker lights.
Good car as-is, anybody wanting a 67 383 has work to do to correct this one and the poor restoration details (painted strikers, washer squirters...)
The body stampings and data tag will tell all.
