Has anyone heard of a 68 1/2 production run?

Sounds like a 68 dashboard and VIN plate were swapped in. Your only course of action is to check the body stamping locations (radiator support and trunk weatherstripping rail) to see if those match the dash VIN. What does the rest of the interior look like?? Is it a '68 or a '69 interior? They are quite different. Possibly a 68 interior (including dash and VIN plate) got swapped into a 69 shell. That's a lot easier than swapping out two quarters, two fenders, plus the grill mounting is different, onto a 68 which makes for too much work. Were two salvaged Darts put together somewhere in the car's past?
