With those side mouldings (introduced 1962), it could be any year from 1962 thru 1967.

The last 6 digits of the VIN is the vehicles specific serial number, decodes to the year and month it was assembled.

Some 1967's used the same oblong taillamps as 1967/72 F100/350 Stylesides, 1969/74 Econolines, 1967/77 Bronco's.

But if no side mouldings are present, and it has round taillamps, tellin' one year from another by lookin' at it is impossible.
