I know it has been 252 days since this thread has been active, but there's a Ford F-Series pickup in the 1976 movie "Car Wash" that has the wrong weight number, and no year:

This is a 1971 Ford F-250, not an F-100.

There's another Ford F-Series that has the year range noted, but it hasn't gone live yet.
